| QHD-2H-2.1G QUAD HYBRID REV: 001, 11/16/06 TECHNICAL DESCRIPTION * 2.0 - 2.3 GHz * LOWEST LOSS * HIGHEST ISOLATION * EXCELLENT PHASE/AMPLITUDE BALANCE * SURFACE MOUNT * TAPE & REEL The Multi-Mix(R) 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. 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.
