CSD-25BH-0.9G

The Multi-Mix® CSD series CSD-25BH-0.9G 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-25BH-0.9G 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.
