Solid State Broadband High Power RF Amplifier
2021 - BBS2E4AHM
20 – 1000 MHz / 50 Watts
The BBS2E4AHM (2021) is suitable for EMI/RFI testing, laboratory, and ultra
broadband high power linear applications. This amplifier utilizes high power push-pull
MOSFET devices that provide high gain, wide dynamic range, low distortions and
good linearity. Exceptional performance, long-term reliability and high efficiency are
achieved by employing advanced broadband RF matching networks and combining
techniques, built in high quality power supply, EMI/RFI filters, machined housings and
all qualified components. Empower RF’s ISO9001 Quality Assurance Program
assures consistent performance and the highest reliability.
