General Description
The HMC346AMS8GE is absorptive Voltage Variable
Attenuators (VVA) in 8 lead surface-mount packages
operating from DC - 8 GHz. It features an on-chip ref-
erence attenuator for use with an external op-amp to
provide simple single voltage attenuation control, 0 to
-5V. 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 cir-
cuits and temperature compensation of multiple gain
stages in microwave point-to-point and VSAT radios.
