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.
