HF power amplifier 1000W 1.8-30 MHz MOSFET VRF2933 in frame
1000W HF MOSFET power amplifier. Operation frequencies 1.8 30 MHz. Input power 29 37 W. Power supply 13.8VDC, 50VDC.
It has two levels of air cooling fan speed: normal and forced. Forced mode is engaged when copper heat spreader plate temperature rise above 50C. If temperature rise above 80C the PTT line is being disabled. Both thermo sensors has 10C hysteresis. Two lines LCD shows the output power in Watts and SWR on output.Second line is output power bar graf. Protection status LEDs are placed on boards, but could be transferred to the front panel. Rear side has 2 coaxial connectors (input and antenna) and 25-pin control. The control connector is used to select the LPF bands and has +13.8V, ALC and PTT inputs also. The amplifier is assembled on aluminum frame, easy to place inside the box of suitable size.
