MERRIMAC QHDZ-2H-2.1G

QHDZ-2H-2.1G
QUAD HYBRID
REV: 003, 05/02/05
TECHNICAL DESCRIPTION
FEATURES
• 2.0 - 2.3 GHz
• LOW LOSS
• HIGH ISOLATION
• EXCELLENT PHASE/AMPLITUDE BALANCE
• SURFACE MOUNT
• TAPE & REEL AVAILABLE
APPLICATIONS
• UMTS BASE STATION
RF SUBSYSTEMS
• SATCOM
The Multi-Mix® QHDZ series provides a 3 dB 90° coupling with low insertion loss, low VSWR, and high
isolation. Accurate phase and amplitude balance make this series ideal for use in IQ networks, power
amplifiers, radio transceivers, receiver multicouplers and RF signal distribution and processing equipment.
QHDZ quad hybrids are fusion bonded multilayer stripline devices. The fusion bonding process yields
a homogeneous monolithic dielectric structure with reliability, ruggedness, and electrical performance
that is superior to conventional adhesive bonding techniques.
