Linearizers
-
Gain Shape Linearizer Amplifiers are used in a number of applications where it's necessary to flatten the gain characteristic of the preceding or following component. This would include flattening the attenuation of a long cable run, or perhaps changing the input gain response to an MPM (Microwave Power Module) or TWT (Traveling Wave Tube) to compensate for the gain variation within the tube.

Crossed-Field Amplifiers
CFAs
-
Communications & Power Industries
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.
