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 control 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.
