QHD-3C-1.11G
QUAD HYBRID
PRELIMINARY REV: 002, 08/22/03
TECHNICAL DESCRIPTION / APPLICATION
MULTI-MIX^® QUADS
The Multi-Mix® QHD series provides a 3 dB coupler with low insertion loss, low VSWR, and high isolation.
Accurate phase and amplitude balance make them ideal for applications involving IQ networks, power
amplifiers, signal distribution and processing equipment.
QHD quad hybrids are fusion bonded multilayer stripline assemblies. The fusion bonding process yields a
homogeneous monolithic dielectric structure with reliability, ruggedness, and electrical performance that is
superior to conventional adhesive bonding techniques.
