Merrimac CSDZ-10SH-2.1G Directional coupler Datasheet

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.
