Model BME1829-50 is a compact solid-state power amplifier (PA) from Comtech Power Systems Technology based on GaN semiconductor technology. The switch-controlled two-band PA provides better than 2 W CW output power from 100 to 500 MHz and more than 50 W CW output power from 800 to 2000 MHz. It incorporates TTL-controlled hot-switchable band control and has enable/blanking time of better than 5 μs.
The class A/AB linear PA integrates a wideband dual directional coupler to simplify system integration. The PA is designed for operating temperatures from -40 to +85°C. It measures 5.5 × 4.5 × 1.6 in. (see figure) and weighs just 1.9 lbs. while meeting MIL-STD-810F requirements for shock and vibration. High-band harmonic rejection is -12 dBc or better while spurious levels are controlled to below -55 dBc. The conduction-cooled PA is designed for use when connected to a heatsink.
