The SSPA models offer 5 to 40 watts of RF power. The inline waveguide combining and modular construction provides a variety of choices to meet custom RF and mechanical requirements. Due to the high linearity of solid-state devices, minimal "back-off" from maximum power is required for multi-carrier or other linear sensitive applications. DC power options provide voltage regulation, biasing, current, and thermal monitoring. Internally, the RF power devices are eutectic soldered to thermally matched Copper Moly (CuMo) carriers which are mounted in aluminum modules.
