3-Port Terminated Waveguide Crossguide Couplers

MCLI’s 3-Port Terminated Waveguide Crossguide Couplers feature excellent performance over the entire waveguide frequency range and optimum directivity through precision internal termination. Each unit is pressurized to 30 psi. Several different configurations in this series are available including a 3-port configuration, a 2 W/G Port/1 NF port configuration, and a 2 W/G port/1 SMA port.

Directional couplers have at least three ports; an input, output, and coupling port. A signal passes between the input and output ports, and a small portion of that signal power applied to the input then passes to the coupling port. The coupling signals are isolated from the line output port to prevent reflections. For more information on this 3-Port Terminated series, download the datasheet.
