Rohde and Schwarz BBA150

The Rohde & Schwarz BBA150 is a solid-state broadband amplifier engineered for research, development, production, and electromagnetic compatibility testing across multiple frequency bands. The modular architecture supports flexible multi-band operation within a single unit, delivering nominal output power from 15 W to 3000 W depending on frequency and model configuration. Built to withstand 100% output mismatch, the BBA150 maintains rated power up to 6:1 VSWR and survives RF short circuits or open conditions without damage.
