General Description

The HMC346C8 is an absorptive Voltage Variable Attenuator (VVA) in a non-hermetic surface-mount ceramic package operating from DC - 8 GHz. It features an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control, 0 to -3V. The device is ideal in designs where an analog DC control signal must con trol RF signal levels over a 30 dB amplitude range. Applications include AGC circuits and temperature compensation of multiple gain stages in microwave radios and test instrumentation.
