The BBS4A5AVT (SKU 2157) is suitable L & S Bands broadband or band
specific high power linear, CW and pulse applications. This amplifier
utilizes high power GaN devices that provide wide frequency response,
high gain, high peak power capability, and low distortions. Exceptional
performance, long-term reliability and high efficiency are achieved by
employing advanced broadband RF matching networks and combining
techniques, EMI/RFI filters, and all qualified components. The amplifier is
housed in two 19” rack mountable cabinets (LRU’s) and as a option can
be supplied in a rack cabinet. The larger LRU (5U) contains the RF power
section while the smaller LRU (3U) contains the main power supply and
control circuits. The system operates from a single phase power supply
and has built in control, monitoring and protection functions and forced air-

cooling system. Empower RF’s ISO9001 Quality Assurance Program

assures consistent performance and the highest reliability.

 Solid-state linear design
 Instantaneous broadband
 Modular LRU design
 Suitable for CW, AM and FM (for other modulation types, consult

factory).

 50 ohm input/output impedance
 High reliability and ruggedness
 Built in Control, Monitoring and Protection Circuits
