Functional Diagram

General Description

The HMC121G8 is an absorptive voltage variable

attenuator provided in a surface-mount hermetic

package. It features an on-chip reference attenua-

tor for use with an external op-amp to provide simple

single voltage attenuation control. The device is

ideal in designs where an analog control signal must

control RF signal levels over a 30 dB amplitude

range, such as in AGC circuits and in temperature

compensation of multiple gain stages.
