Qorvo has introduced four wideband solid-state power amplifiers (SSPAs) designed to replace traveling wave tube amplifiers (TWTAs) in radar, SATCOM, electronic warfare, and test applications.
The new SSPAs provide up to 50 percent smaller system footprint and one-third lower weight compared to legacy TWTAs. They operate from standard 18–24 V power rails, eliminating high-voltage supplies required by TWT systems.
Product specifications:
- QPR3238: 32–38 GHz, >100 W, connectorized module with integrated gain stages
- QPB1840N: 18–40 GHz, 16–32 W, stand-alone SSPA (can drive QPB2040N)
- QPB3238J: 32–38 GHz, 15–20 W, stand-alone SSPA (can drive QPB3238N)
- QPB0618J: 2–18 GHz, 17–40 W, stand-alone SSPA (can drive QPB0220N or QPB0618N)
The Spatium platform uses spatial combining architecture for graceful degradation in case of individual MMIC failure. The SSPAs are field-deployed in airborne electronic warfare systems, including a major U.S. defense program.
