Abstract :
A solid-state amplifier at X band consisting of three cascaded avalanche amplifier stages is described. The amplifier has a gain of 36 dB and a power output of 0.20 watt. A noise figure of 31 dB was measured, using silicon devices in all three stages. Through a combination of microstrip and coaxial circuit techniques a compact unit of 2.5 X 2.5 X 1.0 inches has been obtained. The amplifier operates from a 100-volt supply and consumes approximately 12 watts of dc power.
