DIRECTIONAL COUPLER  
REV: 006, 05/04/05  
TECHNICAL DESCRIPTION  
FEATURES  
410 - 894 MHz  
APPLICATIONS  
• GSM 800 BASE STATION  
• LOW LOSS  
RF SUBSYSTEMS  
• HIGH DIRECTIVITY  
• EXCELLENT COUPLING ACCURACY  
• SURFACE MOUNT

• RADAR COMMUNICATIONS  
• CDMA 450 BASE STATION RF SUBSYSTEMS  
• TV TRANSMITTERS  
The Multi-Mix® CSD series provides 25 dB and 30 dB coupling at 850 MHz and 450 MHz respectively.  
The CSD series features accurate coupling 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 feedforward 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.
