Un-terminated, 4-Port Waveguide Crossguide CouplersSource: Microwave Communications Laboratories, Inc. (MCLI)
Directional couplers are used to isolate, separate, and combine signals in RF signal measurement applications. A signal is passed between an input and output ports, with a smaller portion of the same signal passing to the coupling port.
MCLI’s Un-terminated, 4-Port Waveguide Crossguide Couplers offer -30dB, -40dB, and -50dB coupling with a +/- 0.5 dB nominal coupling. Additional specifications include +/- 1.0dB (max) frequency sensitivity, 20dB (min) directivity, and more. Download the datasheet for more information.
