Functional Diagram

General Description

The HMC346LP3 & HMC346LP3E are pabsorp-

tive Voltage Variable Attenuators (VVA) in low cost

leadless surface mount plastic packages 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 alterna-

tive to the HMC121C8.
