CSDZ-10SH-2.1G DIRECTIONAL COUPLER REV: 002, 10/20/06 TECHNICAL DESCRIPTION FEATURES • 1.9 - 2.3 GHz • LOW LOSS • LOW VSWR • HIGH POWER • HIGH DIRECTIVITY • SURFACE MOUNT • TAPE & REEL The Multi-Mix® CSDZ-SH series provides a 10 dB coupler with low insertion loss, low VSWR, and high directivity. Accurate coupling factors make them ideal for applications involving power amplifiers, signal distribution and processing. CSDZ-SH Directional Couplers are fusion bonded multilayer stripline assemblies. The fusion bonding process yields a homogeneous monolithic dielectric structure with reliability, ruggedness, and electrical performance that is superior to conventional adhesive bonding techniques.
