TECHNICAL DESCRIPTION
FEATURES
• 225 - 400 MHz
• LOW LOSS
• HIGH DIRECTIVITY
• EXCELLENT COUPLING ACCURACY
• SURFACE MOUNT
• Ni/Au Finish
The Multi-Mix® CSDZ series provides 10 dB coupling from 225 - 400 MHz. The CSDZ series features
accurate coupling factors, low VSWR, and high directivity. Very low insertion loss and high power han-
dling capability make this series ideal for use in power amplifiers particularly in the main loop of the feed-
forward amplifiers. The CSDZ series is also ideal for use in RF sampling networks and control circuitry in
high power transmitters.
CSDZ 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.
