General Description
The HMC346 die is an absorptive
Voltage Variable Attenuator (VVA) operating from DC - 20 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 ...
