Crossed-Field Amplifiers (CFAs)

CPI BMD’s crossed-field amplifiers (CFAs) are broadband,
phase-stable microwave amplifiers used in coherent radar chains to efficiently
generate very high peak output powers from relatively low input voltages which can be either
applied to the cathode or an electrode similar to a TWTs cathode or grid pulsing, and in relatively small,
lightweight packages. These characteristics make CFAs particularly well-suited for applications in which the
transmitter must be either airborne, transportable, mobile or portable.

Featuring:
    • Frequencies from 1 GHz to 10 GHz
    • Power levels from 90 kW to 900 kW
Benefits:
    • High peak power
    • Long life
    • Wide band width

Please contact CPI BMD to assist you with your crossed-field amplifier needs.
