General Description

The HMC346LP3(E) is a pabsorptive Voltage Variable Attenuator (VVA) in a low cost leadless surface mount plastic package operating from DC - 14 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. This VVA is an excellent alternative to the HMC121C8.
