1. A waveguide hybrid coupler, comprising:
a waveguide body having a hybrid center portion and defining an H-Plane;
a cavity defined within the waveguide body;
a plurality of ports defined within the waveguide body, wherein the hybrid center portion is disposed between the plurality of ports and each of the ports of the plurality of ports are in communication with the cavity;
a bend along the H-Plane defined within the hybrid center portion, wherein the bend is configured to generate a TE20 mode; and
a septum defined within the waveguide body, wherein the septum is recessed from the hybrid center portion, wherein the septum comprises a chamfered edge.
