QHDZ-2H-0.48G QUAD HYBRID PRELIMINARY REV: 002, 03/16/06 TECHNICAL DESCRIPTION FEATURES • 435 - 524 MHz • LOW LOSS • HIGH ISOLATION • EXCELLENT PHASE/AMPLITUDE BALANCE • SURFACE MOUNT • TAPE & REEL AVAILABLE APPLICATIONS • CDMA 450 BASE STATION POWER AMPLIFIERS • UHF LAND MOBILE RADIO BASE STATION POWER AMPLIFIERS • UHF RADAR (400-500 MHz) The Multi-Mix® QHDZ-2H-0.48G provides a 3 dB 90° coupling with low insertion loss, low VSWR, and high isolation for use in the 435 - 524 MHz range. 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.
