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.
