Abstract :
Present, state-of-the-art, 30 watt, 14-14.5 GHz solid state power amplifier which has been developed and manufactured successfully. The author shows the block diagram of the seven-stage SSPA. This amplifier using four 5.5 watt internally matched GaAs FETs combined in parallel. The amplifier was driven with +12 volt DC-power supply at 40 A and -12 volt at 250 mA. The overall characteristics at 14-14.5 GHz obtained for the seven-stage amplifier was linear gain of 43 dB minimum
