REV 1.0 Page 1 of 4 Copyright © 2017 The FMWCT1109 is a 30 dB WR-137 four port crossguide coupler with one coupled port terminated (making it a three port coupler) and a coax adapter on the opposite coupled port. This coupler can be mounted directly into the waveguide signal path, connected via coax to allow signal sampling / monitoring. The coupler has a typical VSWR of 1.05:1 and are made of bronze with brass UG-344/U Round Cover flanges. The FMWCT1109 is part of a family of cross guide couplers offered by Fairview with coupling values ranging from 20 to 50 dB. There is also a full family of top wall (broad wall) couplers. For the three port version of this coupler (terminated but no coax adapter) please see the FMWCT1037. For the four port version of this coupler (no termination, no coax adapter) please see the FMWCP1072.
