HMC346MS8G / 346MS8GE
GaAs MMIC SMT VOLTAGE-VARIABLE
ATTENUATOR, DC - 8 GHz
v07.1008
General Description
Features
Functional Diagram
Wide Bandwidth: DC - 8 GHz
Low Phase Shift vs. Attenuation
32 dB Attenuation Range
Electrical Specifications, T
A = +25° C, 50 ohm system
Typical Applications
This attenuator is ideal for use as a VVA
for DC - 8 GHz applications:
Point-to-Point Radio
VSAT Radio
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.
