The PEWCT1046 is a 40 dB WR-34 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-1530/U Square Cover flanges. The PEWCT1046 is part of a family of cross guide couplers offered

by Pasternack 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 PEWCT1002. For the four port

version of this coupler (no termination, no coax adapter) please see the PEWCP1037.
