Hittite HMC346LC3B Voltage-Variable Attenuator Datasheet

The HMC346LC3B is a 30dB absorptive Voltage Variable Attenuator (VVA) from Hittite Corporation. It operates from DC to 18GHz and is packaged in a 3 x 3mm SMT package. The device features an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control, 0 to -3V. It is ideal for designs where an analog DC control signal must control RF signal levels over a 30dB amplitude range.
