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 on HF (1kW on 50MHz) 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 (Yaesu and Elecraft K3), and RS-232C (Kenwood). These data cables are optional parts. The one that matches your radio should be purchased separately. 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., -1 - 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. 2-7 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 SETleads to the failure of the final power FET’s (See page 14, Section 10. Trial). In this sense, it is highly recommended that the amplifier is connected to the radio with 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 DC power supply selection is designed with wide AC line voltage technology and works with any voltage of 200V to 250V as well as 100V to 125V. 200V to 250V line, however, is recommended for the best stability and performance. Note that maximum output power is 1kW only, when 100V to 125V is connected. Prepare appropriate AC power cord plug that fits the outlet at your location. 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 - 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 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 MUSTbe shipped using the original box and packaging materials. 3. Features 3-1 Our solid-state broadband design engineers worked to make the HL-2500KFX, the lightest and most compact 1.5 kW amplifier in the industry. This world-class compact 1.5 kW 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. 3-3The amplifier’s main PA section includes 6 high power MOS FET THP2933’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). 3-5With 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 - 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 m…

-37 - １4 Block Diagram and Explanation of Major Circuitry 14-A RF Amp Driving RF signal transmitted from the transceiver is lead to the ATT/ Limitter board via T/R-Assy unit, where there is 3dB attenuator as well as RF limiter. These circuitry properly levels the magnitude of RF signal and also instantly shuts down the input to protect the amplifier. There is a three port splitter located in this board that sprits a driving signal equally into three components, which are then fed to final PA module. PA module consists of three sets of wide band class AB1 linear amp. using THP2933 FET’s in the push-pull form. 500W is achieved per one basic amp. board. Then the three outputs from the PA module is sent to the combiner unit, where three 500W components are combined to become 1,500W. Operating status of three PA’s are strictly monitored in the combiner stage with regard to heat balancing of respective amps. Finally 1,500W of RF output is lead to LPF (low pass filter) unit, where harmonics and spurious signals are reduced to FCC rules. Filtered output signal is sent to T/R ASSY unit again and is lead to antenna terminal by way of antenna relay.
