MERRIMAC QHD-2H-2.3G

QHD-2H-2.3G
QUAD HYBRID
REV: 006, 04/26/05
TECHNICAL DESCRIPTION
• 2.0 - 2.5 GHz
• LOWEST LOSS
• HIGHEST ISOLATION
• EXCELLENT PHASE/AMPLITUDE BALANCE
• SURFACE MOUNT
• TAPE & REEL
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.
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.
