The Multi-Mix® CSD series provides a 5 dB coupling with low insertion loss, low VSWR, and high
directivity. Accurate coupling factors make this series ideal for use in power amplifiers and RF signal distri-
bution and processing equipment.
CSD-5 directional couplers 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.
