The Model C1-C74 series broadband couplers are available with coupling values from 5 dB to 30 dB . Since the couplers are specified over the wide range from 380-4200MHz, they are useful for a wide range of applications from UHF to C band for both systems and other diversified applications. The units are supplied with factory only interchangeable flange connectors for any combination of N, SMA, 4.1-9.5, 4.3-10 or 7-16 DIN connectors, male or female. The couplers utilize a unique tapered stripline construction with wide ground plane spacing with large conductors for exceptionally low insertion loss, high power, (200 Watts plus) and low PIM for communications applications. A 4 port version of the coupler is available for applications where external loads are being used for power or other considerations, or for use as Forward and Reverse bidirectional coupler applications.The model designation for the 4 port option is C1-C74A-xxx
