CSD-10Z-5.5G DIRECTIONAL COUPLER REV: 005, 03/23/05 TECHNICAL DESCRIPTION MULTI-MIX PICO™ Z-SERIES DIRECTIONAL COUPLERS • 5.0 - 6.0 GHz • HIGH POWER…100 WATTS CW • LOW LOSS • LOW VSWR • SURFACE MOUNT • TAPE & REEL 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 distribution 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 performance that is superior to conventional adhesive bonding techniques.
