Linearized Channel Amplifiers

LCAMP

  • Frequency band designs: S-, C-, X-, Ku- and Ka-Band
  • 5 dB typical gain enhancement
  • 40 degree typical phase advance
  • Output power adjustment (6 dB minimum)
  • Low power consumption
  • Weight: < 180 g
  • Blanking mode available 

The channel amplifier can operate in a fixed gain mode (FGM) or an automatic level control (ALC) mode. The unit has commandable gain and ALC levels. Pulse or serial command inputs are used to increase or decrease the gain in the FGM, increase or decrease the power in the ALC mode, and select the mode of operation. An RF telemetry output monitor can be included, which will provide a calibrated DC voltage to provide information on the output power level of the channel amplifier in the FGM. An RF telemetry input monitor can be included, which will provide a calibrated DC voltage to provide information on the input power level of the channel amplifier in the ALC mode.

The unit is constructed using a thin-film amplifier, attenuator, coupler/detector, micro-strip bandpass filter and control circuits. The thin-film modules are enclosed in a laser-sealed, hermetic aluminum housing. The housing has two SMA RF connectors and a 15-pin Micro-D connector for DC/command interface. The linearizer acts as an amplitude and phase predistortion generator to extend the linear operating range of the TWTA.
