The C9534 from Werlatone is a 3-Port Uni-Directional Coupler that operates from 100 to 1000 MHz. This 6 dB coupler provides a directivity of more than 17 dB and has an insertion loss of less than 0.4 dB. It can handle a CW input power of 350 W and has a VSWR of less than 1.30:1. This coupler has a mainline and a coupled line where one end of the coupled line is internally terminated, while the other end serves as a coupled port. Physically reversing the orientation of this coupler can allow it to conduct reverse power measurements. This coupler is available in an Aluminum 6061-T6 module that measures 6.75 x 3.0 x 1.2 inches with N-type (female) connectors and is ideal for sampling and monitoring power in one direction at a given time.
