The Multi-Mix
®
CSD-Z series provides directional couplers with low insertion loss, low VSWR, and high
directivity. Accurate coupling factors make this series ideal for use in power amplifiers and RF signal dis-
tribution and processing.
CSD-Z directional couplers are fusion bonded multilayer stripline devices. The fusion bonding process
yields a homogeneous monolithic dielectric structure with reliability, ruggedness, and electrical perform-
ance that is superior to conventional adhesive bonding techniques.
