General Description

Functional Diagram

The HMC346ALC3B is an absorptive Voltage Variable

Attenuator (VVA) in a leadless “Pb free” RoHS com-

pliant SMT mount ceramic package operating from

DC - 18 GHz. It features an on-chip reference atten-

uator for use with an external op-amp to provide

simple single voltage attenuation control, 0 to -5V.

The device is ideal in designs where an analog DC

control signal must control RF signal levels over a

30 dB amplitude range. The HMC346ALC3B allows

the use of surface mount manufacturing techniques.
