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.
