UB9HL-25KFXHigh Power Amplifier

INSTRUCTION MANUAL HF LINEAR POWER AMPLIFIER MODEL : HL-2.5KFX 1 1. Introduction Thank you for purchasing the HL-2.5KFX. This compact and lightweight desktop HF linear power amplifier has a maximum input power of 2.9 kW. Our solid-state broadband power amp technology makes it the smallest and lightest in the industry. Typical output power is 1.5 kW PEP/SSB with the drive power of 85-90 W. The built-in band decoder will let you forget about the band setting when the amplifier is connected to your modern radio through such band data cables as ICOM CI-V, DC voltage (ICOM, Yaesu), and RS-232C (Kenwood). All the data cables are included in your amplifier for your convenience. 2. Cautions 2-1 Unpack the amplifier, check the fan guard at the rear panel Fan to see if there is any damage caused by the physical shock during the transportation. Fan blades must be free to rotate when powered. The amplifier is cooled by forced airflow. Several inches of clearance on the top and the rear wall are necessary to allow for smooth air intake into the fan. Do not block the air vents on the top cover. 2-2 Keep the amplifier out of direct sunlight, in a cool dry environment. 2-3 Internal high voltages, (AC, DC and RF), are present at all times, ON AIR or OFF. Internal access should be limited to avoid injury. 2-4 Turn off the AC main power immediately upon any unusual sounds, sights or odors. Check the multimeter readings of Vd and Id, the fuses and all cable connections around the amplifier. Please notify the dealer or the factory of any problems. 2-5 For your safety, do not operate the amplifier without adequate grounding. A proper ground connection will result in peak performance and stability, in addition to reduced RF strays or noises. 2-6 To eliminate the RF interference to such home appliances as TV, FM radio, telephone sets, etc., it is recommended that clamp-on ferrite cores be 2 inserted at both ends of the remote control cable, ALC cable, coaxial jumper cable, and antenna cables, as needed. Also, a common mode AC line filter (near the AC outlet), and in-line low pass filters on the antenna coaxial cable, (as necessary), are recommended. 2-7 The amplifier has fast acting sophisticated protection circuits controlled by the latest microprocessor technology. Please note, however, any such actions that cause the same fault to occur repeatedly, will lead to failure of the valuable final power FET transistors. Also note that the full power CW (or carrier) drive under the erroneous MANUAL BAND SET leads to the failure of the final power FET’s (See page 11, Section 7. Connection). In this sense, it is highly recommended that the amplifier is connected to the radio with supplied Band Data Cable. 2-8 Before checking inside the amplifier, be sure to wait a few minutes for the high DC voltage to discharge (monitor Vd meter reading). The internal potentiometers for RF power detector, protection circuits, FET bias voltage circuit, etc., are precisely adjusted at the factory, and should not be altered. Doing so, would require readjustment with precision measuring instruments. 2-9 The primary power transformer is factory pre-wired for AC 240 V operation. (See page6, Section 5. AC Line Voltage) Be sure to verify your AC line voltage before you plug the AC power cord into the outlet. 2-10 Before powering on the amplifier, be sure to connect a dummy load (50 ohms, 1.5 kW min.) or a well-adjusted antenna to the output terminal. Operating without any load will cause extreme stress to the RF power FET’s, although protection circuits should work under critical conditions. 2-11 Required drive power is slightly less than 100 W to obtain the full 1.5 kW output. Do not attempt to operate with excessive drive from a high power transceiver. Transmitting high drive RF (over 100 W) into the amplifier will void the warranty. 2-12 Keep the aluminum heat sink and air openings free from dust and blockages. Periodic cleaning will prevent degraded cooling efficiency. 3 2-13 For long continuous operation in RTTY/FM modes, it is recommended you reduce the RF drive levels by 20% to 30% lower output than CW/SSB modes. 2-14 To prevent damage to the precision electronic components, avoid extreme physical shock to the amplifier. If factory service is required, the amplifier MUST be shipped using the original box and packaging materials. 3. Features 3-1 Our solid-state broadband design engineers worked to make the HL-2.5KFX, the lightest and most compact 1.5 kW HF amplifier in the industry. This world-class compact 1.5 kW HF amplifier is the easiest to handle and operate. 3-2 The amplifier is equipped with a newly developed band decoder. The amplifier’s decoder changes bands automatically as the data signal is received from the associated HF transceiver’s frequency bands. 3-3 The amplifier’s main PA section includes 2 high power MOS FET ARF1500’s by Microsemi, resulting in 1.5 kW PEP (SSB max.). The amplifier’s broadband characteristics require no further tuning once the operating band is selected. 3-4 The amplifier allows operation in full break-in CW mode due to the use of the amplifier’s high- speed antenna relays (made by Panasonic/Matsushita). 3-5 With the unique duct structure design and the powerful blower fan, the aluminum heat sink block for RF PA module (and other components), are effectively cooled. The fan’s quiet operation allows for even the weakest DX signals to be heard. 3-6 The amp utilizes an advanced 16 bit MPU (microprocessor) to run the various high speed protection circuits such as overdrive, high antenna SWR, DC overvoltage, band miss-set etc. 4 3-7 This amplifier is compatible with AC 220 V and 240 V (200/230/250 V included). See the illustration in the AC Power Section for changing primary wiring of the power transformer. 3-8 For the safety of the operator, an Interlock system is employed. The AC power is shut down if the top cover is removed, and the automated safety interlock is activated. 3-9 An analog multimeter al…

Model HL-2.5KFX Explanation on Band Inhibit Circuit (26.028.0 MHz) 1. RF drive signal from the transceiver is detected by the RF IN detector, T501 in DET AND T/R RELAY board (PC1398B), and is sent to FREQ SAMPLER board, Unit 12. 2. In the Unit 12, the signal is amplified by RF AMP (ERA-5). Then the signal is transferred to CPU board (PCS1679), after the waveform treatment by IC 74HC14. 3. Frequency counting is made by CPU, 18F452 of CPU board. If the signal frequency is within the range of 26.0 to 28.0 MHz, “PROT INHBT-FREQ” is displayed on the LCD panel, and the amp is set in the transmission inhibit mode. When this inhibit mode works, PROT LED lights and OPER LED goes off. T/R relays of both K501 and K502 become open, and the transmitting signal from the transceiver will bypass the amplifier. Also, DC supplies for VDD and bias voltage are suspended, and the amplifier gets shut down. 4. The shut down can be reset, if the OPER switch is turned off and on.

Model HL-2.5KFX-Theory of Operation(How It Works/ RF Signal Flow)- 1/2 Model HL-2.5KFX Theory of Operation How It Works/ RF Signal Flow When the amplifier is in a stand-by (STBY) mode, gate bias(voltage) to the final FET’s are cut off. Also input(TX) relay and output(ANT) relay are free(open) from the amplifier. Therefore the signals from the transceiver and/or from the antenna will all by-pass the amplifier. (By-Pass/ Stand-By Mode) When the amplifier is in an OPER.(operate) mode and keyed by the transceiver, forward gate bias is applied to the final power FET’s and at the same time input and output relays are closed to the IN and OUT of the amplifier. Consequently the amplifier is ready to work with the designed amplification gain. RF Drive signal from the transceiver reaches RF IN of DET(Detector) & T/R Relay Unit, PC1398B (Unit 5), where input power level is measured. If the in drive power is over 100W, the protection circuit commanded by micro computer (CPU) installed in PCS1677 (Unit 1) will issue a command of “Over-Drive”, to shut down the amplifier. DET UNIT also measures the amplified output level of the amplifier. When the ratio of output and input(drive) powers is much lower than the designed value, CONT UNIT(PC1698) will judge that final amplifier is out of order and/or that output LPF (low pass filter) is band miss-set. Drive signal having passed INPUT DET part is sampled by Unit 12, Freq. DET UNIT, where the frequency of the drive signal is counted by IC. If the frequency is between 26.0 and 28.0 MHz, CONT(ROL) UNIT issues the command to shut down the amplifier, according to FCC rule. Then drive signal reaches the input of POWER AMP UNIT 6, PC1661. Signal is attenuated by 2 dB attenuator before entering the gates of Model HL-2.5KFX-Theory of Operation(How It Works/ RF Signal Flow)- 2/2 FET’s. Two FET’s (ARF1500’s) form a broad-band push-pull linear amp with a gain of approximately sixteen times. Next, the amplified signal will pass through LPF(low pass filter) UNIT (Unit 9), PC1681, where the harmonics are filtered and removed. Filtered output signal will then go through the OUT DET(output power detector) of DET UNIT, PC1398B to reach RF OUT, J3(ANT) terminal. OUT DET measures the output power level of the signal. This power level is shown on the analog multi-meter, PF scale(forward power).

Model HL-2.5KFX-Product Explanation and About Its Major Circuitry- 2/8 2. PA PA consists of a pair of Microsemi ARF1500, in class AB push-pull configuration. Drain conditions are, VDD = 100V IDQ (when with no drive) = 250 mA/each FET To achieve the gain flatness over the designed frequency range, multiple loops of NFB are applied, NFB from a coupling coil to T2, DC power feeding transformer. NFB from Drain to Gate of FET. Impedance transformation ratio of input transformer, T1 is frequency switched for either 4 to 1, or 5 to 1 of winding ratio. 16A fuse is equipped in each drain current pass so that the whole system is shut down when the sensor detects a blown fuse.

Input Limiter Circuit/ Bias Circuit To set the input (drive) power level of the amplifier to be 100W, 3dB power attenuator is built in the input side. Also, there are RF diode switch (D1, D2) connected in parallel with PA circuit. These diodes make a fast shut down of the RF drive signal, working in combination with the protection system. When this protection circuit works, forward current flows in the diodes making a short circuit across the input terminal of PA and the ground. The attenuator resistor, at this time, becomes a protection resistor towards the driving source (transceiver) and shows input SWR of 2. Fuse F1 has been put in series with the attenuator as an additional protective means for the PA. Shunt regulator IC, TL431 is used in the bias circuit, that is temperature compensated with a thermistor. Bias output is shut down through a photo-MOS FET for the purpose of fast send-receive switching. Model HL-2.5KFX-Product Explanation and About Its Major Circuitry- 4/8 4. Input Equalizer Just in front of the PA, there is an input equalizer. It contributes to the gain flatness over the designed frequency band width as well as to IMD improvement and prevention of parasitic oscillation. The equalizer is basically a bridged L/C network. Model HL-2.5KFX-Product Explanation and About Its Major Circuitry- 5/8 5. Main DC Power Supply and Safety Circuit AC mains are indirectly turned on by the Main Relay. In series to this relay, there are connected thermal switches for PA heat sink (100) and power transformer (130) that work independently from other electronic protection circuits. Threshold values are set much higher than other protections, and they do not turn on in the normal operating conditions. AC line filter has 15 amps of current capacity. Capacitance against ground is 2,200pF per phase. AC rectification for drain DC voltage is made through diode bridge, and is filtered with 18,000F of electrolytic capacitor. This power supply system works from AC line voltages of 210V through 250V only.

Transmitting RF Signal Pass When the amp is keyed, IN/OUT antenna relays are closed and amplified signal will reach ANT terminal. When RX and/or when amp is at STBY, the relays become open to make a thru-line pass between TRX and ANT. Both at input side and output side of PA, there are RF directional couplers that monitor incoming drive power, outgoing forward power, and reflected power from the load. To comply with FCC rule (26.0-28.0 MHz inhibited), incoming RF signal is sampled by RF power detector, and is transferred to the frequency detector system comprised of MPU.

1 7. Operation ***CAUTION: Under the Manual Band Set operation, always be sure to check if BAND Switch position matches that of your radio before keying PTT or the CW paddle. Also when you have changed the BAND, do not make the full power CW (carrier) drive but reduced level power to see if the BAND is set correctly and the amplified RF power comes out properly. Full power CW drive under the BAND Mis-set leads to the failure of the valuable final power FET devices. *** 8-1 Various Status There are four modes to be displayed on LCD. STBY (Standby Mode) This mode is for AC Power ON, and OPER. Switch at STBY position. Amplifier is in a through state. OPER (Operate) Mode This mode is for AC Power ON, and OPER switch at OPER. Position. Amplifier will work, if the transceiver is keyed. ONAIR (On Air) Mode This is for amplifier being keyed under OPER. Mode. Amplifier is amplifying or ready to amplify the drive signal. PROT (Protection) Mode Amplifier has been shut down by the protection circuit and is in a though state. See page 19, Section11. Protection Circuits on how to reset. 8-2 How to Operate 8-2-1 Connect AC cord and coax cables as illustrated in Section 7 Connection. Connect the cable from “SEND” to ACC or the remote terminals of transceiver, where it is marked “SEND” or “TX GND”. These terminal pins are shorted to ground when the transceiver is in TX/ON AIR mode. If these connections are not made, the amplifier will not go into TX (amplification) mode. For a temporary check to the amp, ground the SEND center pin by inserting an RCA plug whose center pin has been soldered to the outer case of the plug with a small piece of wire. As a side note, this SEND terminal shows 12 VDC when open, and draws 35 mA when shorted. 8-2-2 At first, turn the ALC knob full clockwise to avoid ALC voltage to the transceiver. Application of ALC will be covered in the following Section 9. 8-2-3 Keeping the POWER (AC mains) switch off, check the SWR of your antenna by keying the transceiver to TX mode (CW or RTTY mode). Monitor the SWR with an external SWR/Power meter. If SWR is 1.8 or higher at band center, the antenna has to be adjusted for lower SWR.. As an alternative, an antenna tuner may be inserted. 8-2-4 While keeping OPER/STBY switch at STBY position, turn the POWER switch on. Turn BAND AUTO-MAN’L switch to AUTO, or MAN’L(manual) position. If MAN’L is selected, turn BAND-MAN’L switch to desired band. See page 17, Section10. Band Data Cable Connection, for more details of various band data cables. Turn the STAND-BY switch to OPER (operate) position and the amplifier is ready to go. If the POWER switch is turned on, while OPER/STBY switch is at OPER(operate) position, the orange OPER lamp will blink, and you will need to reset the OPER switch to enter into operation mode. “PSE STBY OPERSW is displayed at this time. If you key the transceiver with the carrier level set relatively low (such as 20-30W), you will achieve an amplified output signal of a few hundreds watts. Monitor this output with the PF meter or with an external power meter. Increase drive level to roughly 50W and see if the antenna SWR stays constant. (As higher RF currents flow some antennas may show a changed SWR value due to heated connector junctions and trap coils.) 8-2-5 You can now increase the drive level to nearly 80-90W to achieve maximum carrier output power of 1.4 kW (CW, RTTY) from the amplifier. If you change to SSB mode, peak voice power will reach approximately 1.5 kW. For high duty cycle transmissions like RTTY, SSTV, or FM modes, it is recommended you reduce the drive power by 20-30 % compared with SSB/CW. 8-2-6 With a high power transceiver in SSB mode, you can overdrive the amplifier resulting in a distorted output signal. This can also occur if you speak too loud or if you set the microphone gain too high. Speak into the microphone properly to reduce the possibilities of splattering into the neighborhood. The ALC is effective in preventing the output signal from being distorted or to limit the carrier level to within rated output levels. As long as you do not overdrive, you can disregard the ALC connection. See page 15, Section 9. ALC Connection for details. 8-7-7 Protection circuits may work during operation depending on the conditions. If the protection circuit has shut down the amplifier, check the antenna SWR, Vd, AC line voltage, or try to reduce the drive level. To reset, turn off the OPER/STBY switch once, then back on again. Note that some protection modes need to reset the POWER switch(See page19, Section 11. Protection & Safety Circuits for more details). The power transformer has an overheat protection(130) in the coil layer. If this temperature switch activates, the amplifier will put you in receive mode with the cooling fan operating until the transformer has cooled off. It may take ten to fifteen minutes to cool, depending upon room temperature. In the same way, there is a built-in thermal switch (100) in the heat sink block of power FET’s.
