The C10748 from Werlatone is a 4-Port Dual Directional Coupler that operates from 2000 to 6500 MHz. This 60 dB coupler has more than 15 dB of directivity and an insertion loss of less than 0.2 dB. It can handle a CW input power of 500 W and has a VSWR of less than 1.35:1. The coupler has been built using two 3-Port uni-directional couplers internally connected in tandem providing measurement of both forward and reverse power. The directivity of this dual directional coupler is unaffected by the loads on the coupled ports. It is available in a module that measures 2.15 x 2.00 x 1.36 inches and has 7/16 (male/female), N-type (female) or SMA connector options. This coupler is ideal for simultaneously monitoring a system’s forward and reverse power and for reflectometer measurements.
