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.

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.
