CSD-10M-3G
DIRECTIONAL COUPLER
REV: 007, 09/03/04
TECHNICAL DESCRIPTION
FEATURES
• 2.0 - 4.0 GHz
• LOW LOSS
• HIGH DIRECTIVITY
• EXCELLENT COUPLING ACCURACY
• SURFACE MOUNT
APPLICATIONS
• WCDMA BASE STATION
RF SUBSYSTEMS
• SATCOM
The Multi-Mix^® CSD series provides a 10 dB coupling with low insertion loss, low VSWR, and high
directivity. Accurate coupling factors make this series ideal for use in power amplifiers and RF signal dis-
tribution and processing.
CSD - 10 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.
