CSD series provides a 30 dB coupling with low insertion loss, low VSWR, and high direc-
tivity. Accurate coupling factors make this series ideal for use in power amplifiers and RF signal
distribution and processing equipment.
CSD - 30 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.
