Model BHCDP928978-4000 is a GaN amplifier for ground or surface X-band radar applications. The Class AB linear design operates from a 9.2 to 9.7 frequency range over an instantaneous bandwidth of 500 MHz. It was developed as a TWT replacement. The amplifier design features self protection for load VSWR, duty factor, pulse width, and temperature, as well as a graceful degradation in case of a RF power module failure. An MTBF increase of 10 times that of the TWT is achieved for greatly improved reliability and lower maintenance costs. Other features include excellent efficiency, RF input and output sample detectors, remote status/control interface (Ethernet), and ruggedization for harsh environmental applications. The company supports custom configurations and features are available as well as specific power levels up to 16kW.
