Dolph Microwave's waveguide tee in microwave is four-port coupler for matching, balance, and isolation. E-plane to H-plane Isolation is a function of the symmetry which is carefully balanced on each unit. If the E-plane port 4 or the H-plane port 2 are used as inputs the split is on the output collinear ports 1 and 3. When the input is E plane port4 the outputs are out of phase 180 deg. When the input is H plane port 2 the outputs are in phase. The in-phase and equal amplitude signals inputting into two collinear ports can result combined signals at H-plane port and canclle dsignal at E-plane port. This feature is widely used in monopulse antenna feeds structure and phasing testing setup. Taking waveguide tee in microwave as example.

**Typical operating bandwidth of the hybrid tee is up 20% of waveguide bandwidth. Performance degradation may occur while it covers wider waveguide bandwidth.
Waveguide Tees in Microwave is divided in H-tee and E-tee. E-tee is only like a power divider while H-tee is almost the similar function like 2-way divider from the application. Waveguide Tees in Microwave is different from neither H-tee and E-tee, which is also functional as divider but it is 4-port components.
Waveguide Tee is used to either divide or combine power in a waveguide system which is similar like a power divider. It is a 3-port components and when three waveguides tubes are connected which is like "T". So the components naming as waveguide tee.
