HMC121 - GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR

General Description

The HMC121 chip is an absorptive voltage variable attenuator.

Key Features

  • an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control. The device is ideal in designs where analog control signal must control RF signal levels over a 30 dB range, such as AGC circuits and in temperature compensation of multiple gain stages.

MICROWAVE CORPORATION HMC121 General Description The HMC121 chip is an absorptive voltage variable attenuator. It features an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control. The device is ideal in designs where analog control signal must control RF signal levels over a 30 dB range, such as AGC circuits and in temperature compensation of multiple gain stages. Applications include military ECM and communications as well as commercial microwave radios and VSAT. See SMT packaged version HMC121G8 (hermetic).
