We describe a matched waveguide power divider/combiner consisting of an E-plane folded hybrid-T with a terminated coaxial fourth port. It is made as a split block and can be scaled for use in any band. For a WR-10 prototype, the input return loss was greater than 19 dB across the waveguide band, and the isolation and output return loss greater than 14 dB.
