A waveguide cavity 180 deg hybrid coupler with coaxial ports

We describe the design, construction, and performance of a 180 deg hybrid coupler for the frequency band 1.3-1.8 GHz (L-band). The hybrid utilizes a WR650 rectangular waveguide cavity and has three 50 coaxial ports. The signals are coupled in and out of the cavity through broadband coaxial probes at...

Zusammenfassung:We describe the design, construction, and performance of a 180 deg hybrid coupler for the frequency band 1.3-1.8 GHz (L-band). The hybrid utilizes a WR650 rectangular waveguide cavity and has three 50 coaxial ports. The signals are coupled in and out of the cavity through broadband coaxial probes attached to 7/16-type connectors. The measured performances are in excellent agreement with the electromagnetic simulations.
