DIRECTIONAL COUPLER

REV: 001, 05/26/05

TECHNICAL DESCRIPTION

FEATURES

380 - 520 MHz

• LOW LOSS

• HIGH DIRECTIVITY

• EXCELLENT COUPLING ACCURACY

• SURFACE MOUNT

APPLICATIONS

•

• LAND MOBILE RADIO (LMR) SYSTEMS

• RADAR COMMUNICATIONS

• CDMA 450 BASE STATION

RF SUBSYSTEMS

• TV TRANSMITTERS

The Multi-Mix^®CSD series provides 20 dB coupling at 450 MHz. The CSD series features accurate cou-

pling factors, low VSWR, and high directivity. Very low insertion loss and high power handling capability

make this series ideal for use in base station power amplifiers particularly in the main loop of the feedfor-

ward amplifiers. The CSD series is also ideal for use in RF sampling networks and control circuitry in

high power transmitters.

CSD directional couplers are based on fusion bonded multilayer stripline structures. The fusion bonding

process yields homogeneous monolithic dielectric structures with reliability, ruggedness, and electrical

and thermal performance that are superior to conventional adhesive bonding techniques.
