Solid State Power Amplifiers
Airborne SSPASolid State Transmitter for APG-66


Replace legacy tube-based transmitters with high MTBF GaN solid-state power amplifiers (SSPAs).

Duotech Services provides a range of SSPAs which conform to multiple aircraft’s size, weight, power, and cooling constraints. Our SSPAs are designed with MTBF in mind, ensuring that they can withstand the rigors of air travel. By replacing legacy tube-based transmitters with our SSPAs, you can be confident that your aircraft will have the power it needs to stay airborne.
