QHDZ-2P-0.064G QUAD HYBRID REV: 001, 12/10/09 TECHNICAL DESCRIPTION FEATURES • 64 MHz • LOW LOSS • HIGH ISOLATION • EXCELLENT PHASE/AMPLITUDE BALANCE • HIGH POWER HANDLING • SURFACE MOUNT APPLICATIONS • ANTENNA FEEDS • POWER AMPS The QHDZ-2P-0.064G series is a member of the Multi-Mix QHD family of 3-dB 90° couplers for use in the .054-.074 MHz range. The QHDZ-2P-0.064G 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 power amps and antenna feeds systems. The construction of QHD quad hybrids is based on fusion bonded multilayer 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.
