The C8671 from Werlatone is a 3-Port Uni-Directional Coupler that operates from 300 to 3000 MHz. It has a coupling factor of 10 dB ± 1 dB and a directivity of more than 15 dB. The coupler has an insertion loss of less than 0.35 dB. It can handle an average input power of 100 W CW and has a VSWR of 1.2:1. This directional coupler consists of a main line and a coupled line. One end of the coupled line is internally terminated, while the other end serves as a coupled port. It is available in a compact connectorized module that measures 3.7 x 2.0 x 0.75 inches with N-type female and SMA connectors. This RoHS-compliant coupler is ideal for sampling and monitoring power in one direction at a given time. It is necessary to physically reverse the orientation of the unit to change from a forward to a reverse power measurement.
