The Multi-Mix
®
CSDZ-SH series provides a 20 dB coupler with low insertion loss, low VSWR, and high
directivity. Accurate coupling factors make them ideal for applications involving power amplifiers, signal
distribution and processing.
CSDZ-SH Directional Couplers are fusion bonded multilayer stripline assemblies. The fusion bonding
process yields a homogeneous monolithic dielectric structure with reliability, ruggedness, and electrical
performance that is superior to conventional adhesive bonding techniques.
