| QHDZ-2N-0.45G QUAD HYBRID REV: 004, 06/15/06 TECHNICAL DESCRIPTION FEATURES * 380 - 520 MHz * LOW LOSS * HIGH ISOLATION * EXCELLENT PHASE/AMPLITUDE BALANCE * HIGH POWER HANDLING * SURFACE MOUNT APPLICATIONS * CDMA 450 BASE STATION POWER AMPLIFIERS * UHF LAND MOBILE RADIO BASE STATION POWER AMPLIFIERS * UHF RADAR (400-500 MHz) The QHDZ-2N-0.45G series is a member of the Multi-Mix QHDZ family of 3-dB 90 couplers for use in the 380-520 MHz range. The QHDZ-2N-0.45G exhibits low insertion loss, low VSWR, and high isolation. Excellent phase and amplitude balance and high RF power handling capability make this series ideal for use in base station power amplifiers in particular and radio transceivers, receiver/antenna multicouplers and RF signal distribution and processing equipment in general. The construction of QHDZ quad hybrids is based on fusion bonded multiplayer stripline structures. The fusion bonding process yields homogeneous monolithic dielectric structures with reliability, ruggedness, and electrical and thermal performance that are superior to conventional adhesive bonding techniques.
