Functional Diagram
General Description
The HMC346C8 is an absorptive Voltage Vari-
able 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.
