QHDZ-2N-0.9G QUAD HYBRID REV: 001, 08/19/05 TECHNICAL DESCRIPTION FEATURES • 740 - 960 MHz • LOW LOSS • HIGH ISOLATION • EXCELLENT PHASE/AMPLITUDE BALANCE • SURFACE MOUNT • TAPE & REEL AVAILABLE APPLICATIONS • GSM 850 RF SUBSYSTEMS • GSM 950 RF SUBSYSTEMS • LAND MOBILE RADIO (LMR) • RADAR COMMUNICATIONS • HOMELAND SECURITY NETWORKS • PUBLIC SAFETY BTS AMPLIFIER 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.
