Abstract

The invention provides a compact structure T-type orthogonal mode converter and a waveguide duplexer composed of the compact structure T-type orthogonal mode converter. The compact structure T-type orthogonal mode converter comprises a common port, a horizontal polarized wave port and a vertical polarized wave port; and the horizontal polarized wave port and the vertical polarized wave port respectively excite mutually orthogonal fundamental mode signals transmitted by the common port. The horizontal polarized wave port and the vertical polarized wave port are respectively connected with a horizontal polarization duplexer and a vertical polarization duplexer to form the overall integrated waveguide duplexer. The T-type orthogonal mode converter has the advantages of simple structure and the small size, greatly reduces the engineering quantity, and then reduces cost. The waveguide duplexer composed of the compact structure T-type orthogonal mode converter can be applied to 6GHz, 10GHz, 13GHz, 15GHz, 18GHz, 23GHz, 26GHz, 28GHz, 32GHz, 38GHz and other frequency bands digital microwave communication outdoor systems, and also can be applied to other digital microwave communication systems.
