HMC346MS8G

346MS8GE

v05.0607

GaAs MMIC SMT VOLTAGE-VARIABLE

ATTENUATOR, DC - 8 GHz

Typical Applications

Features

Wide Bandwidth: DC - 8 GHz

Low Phase Shift vs. Attenuation

32 dB Attenuation Range

ATTENUATORS - SMT

This attenuator is ideal for use as a VVA

for DC - 8 GHz applications:

• Point-to-Point Radio

• VSAT Radio

Functional Diagram

General Description

The HMC346MS8G & HMC346MS8GE are absorp-

tive Voltage Variable Attenuators (VVA) in 8 lead sur-

face-mount packages operating from DC - 8 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 con-

trol RF signal levels over a 30 dB amplitude range.

Applications include AGC circuits and temperature

compensation of multiple gain stages in microwave

point-to-point and VSAT radios.
