UB9HL-550FX550W HF LINEAR AMPLIFIER

Users Manual Solid-State HF/50MHz Band 550W Linear Power Amplifier Model HL-550 FX 1 1. Introduction Thank you for purchasing the HL-550FX. This compact and lightweight desktop HF linear power amplifier has a maximum input power of 1.2kW. Our solid-state broadband power amp technology makes it the smallest and lightest in the industry in its class. Typical output power is 550W (SSB, CW) with the drive power of 65-90W. It is best suited for the DX-pedition use due to its light and compact design. 2. Cautions 2-1 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, and etc., it is recommended that clamp-on ferrite cores be 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 2-7 The amplifier has fast acting sophisticated protection circuits. 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. 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 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 DC power supply section consists of most efficient and sophisticated switching mode circuit. It accepts the wide AC line voltages ranging from AC 100V up to 260V. Since the line voltage is detected and selected automatically, you do not have to worry about the tap change of internal power transformer whichever country you will travel. Be sure to verify capacity of AC line fuse before you plug the AC power cord into the outlet. 2-10 Before starting the amplifier, be sure to connect a dummy load (50 ohms, 550W 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 100W to obtain the full 550W output. Do not attempt to operate with excessive drive from a high power transceiver. 2-12 Keep the aluminum heat sink and air openings free from dust and blockages. Periodic cleaning will prevent degraded cooling efficiency. 2-13 For long continuous operation in RTTY/FM modes, it is recommended that 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 should be shipped using the original box and packing materials. 3 3. Features 3-1 Our solid-state broadband design engineers worked to make the HL-550FX, the lightest and most compact 550W out portable HF/50MHz amplifier in the industry. This world-class compact 550W HF amplifier is the easiest to handle and operate anywhere in the world. 3-2 The amplifier’s main PA section includes 4 high power MOS FET VRF150, resulting in 550W (SSB/CW max.) on HF and 50MHz bands. The amplifier’s broadband characteristics require no further tuning once the operating band is selected. 3-3 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). 3-4 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. 3-5 The amp utilizes a sophisticated circuit to run the various high speed protection circuits such as overdrive, high antenna SWR, DC overvoltage, band miss-set etc. 3-6 This amplifier is compatible with wide AC line voltage ranging from AC 100V to 260V. Although AC line voltage is automatically selected, be sure to install proper fuse into AC line fuse holder. 3-7 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. 3-8 An analog multimeter allows the operator to monitor Pf (Forward output power), Pr (Reflected power), Vd (Drain voltage of power FET), Id (Drain current) etc. 4 4.

Model HL-550FX Explanation on Band Inhibit Circuit (To prohibit 26.028.0 MHz) Drive signal from the transceiver is, at first, received by the (RF) DET UNIT PC1821 and then transferred to PCS1733, FREQ. DETECTOR CIRCUIT. The signal is divided by sixteen (16) through the prescaler IC1, TD7101F. The resulting signal is sent to the IC2, PIC micro processor, where the signal frequency is counted If the drive signal is judged to fall in the band width of 26.0 to 28.0 MHz, IC2 issues the command to open the relay RL1, of which contacts are in series with the STAND-BY (STBY/OPER.) control circuit, as is shown around T/R pin of PC1818, CONT’L UNIT and STBY, RCA-Jack located at the rear panel of the amp. Once the STAND-BY control circuit becomes open, the amp keeps stand-by mode and amplifier gain is nil, even if it is driven by out of amateur band signals between 26.0 and 28.0 MHz.

Model HL-550FX-Theory of Operation(How It Works/ RF Signal Flow)- 1/2 Model HL-550FX 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 at the IN and OUT terminals of the amplifier. Consequently the amplifier is ready to work with the designed amplification gain. RF Drive signal from the transceiver reaches RF IN (J504) of DET (Detector) Unit, PC1821, where input power level is measured. If the in drive power is over 100W, the protection circuit 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 (PC1818) 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 will be lead to PC1733, 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 PA UNIT, PC1662V. Signal is attenuated by 6 dB attenuator before entering the gates of FET’s. Four FET’s (VRF150’s) form a broad-band parallel push-pull linear amp with a gain of approx. forty (40) times. Model HL-550FX-Theory of Operation(How It Works/ RF Signal Flow)- 2/2 Next, the amplified signal will pass through LPF (low pass filter) UNIT, PC1817, where the harmonics are filtered and removed. Filtered output signal will then go through the OUT DET (output power detector) of DET UNIT, PC1821 to reach RF OUT, J505 (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). This amplifier has two sets of built-in DC power supply units. They are commercially made switching mode DC P.S. that work over the wide AC voltage range, i.e. AC 85V264V. The DC power supply section is solidly shielded and filtered to avoid the leakage of switching noises over the wide frequency range. ADF1000F48 provides DC42V/20A to the drains of final power FET’s. KWD15-1212 provides +12V and -12V to the various low voltage circuits and control circuits.
