Wide Bandwidth: DC - 8 GHz
Low Phase Shift vs. Attenuation
30 dB Attenuation Range
Surface Mount Ceramic Package
Electrical Specifications, T
A = +25° C, 50 ohm system
Typical Applications
The HMC346C8 is ideal for:
Basestation Infrastructure
Fiber Optics & Broadband Telecom
Microwave Radio & VSAT
Military Radios, Radar, & ECM
Test Instrumentation
The HMC346C8 is an absorptive Voltage Variable
Attenuator (VVA) in a non-hermetic surface-mount
ceramic package operating from DC - 8 GHz. It fea-
tures 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
radios and test instrumentation.
