GaAs MMIC VOLTAGE-VARIABLE
ATTENUATOR, DC - 14 GHz
General Description
Features
Functional Diagram
Wide Bandwidth: DC - 14 GHz
Low Phase Shift vs. Attenuation
30 dB Attenuation Range
Simplified Voltage Control
3 x 3 x 1 mm SMT Package
Electrical Specifications, T
A = +25° C, 50 ohm system
Typical Applications
The HMC346LP3 / HMC346LP3E is ideal for:
Basestation Infrastructure
Fiber Optics & Broadband Telecom
Microwave Radio & VSAT
Military Radios, Radar, & ECM
Test Instrumentation
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.
