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.
