The Multi-Mix

®

QHD 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.

QHD 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.
