The HMC346LC3B is an absorptive Voltage Variable Attenuator (VVA) in a leadless Pb free RoHS compliant SMT mount ceramic package operating from DC - 18 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. The HMC346LC3B allows the use of surface mount manufacturing techniques.
