Abstract

The invention discloses an S-band miniature double-microwave external load orthogonal power divider, which comprises an external load directional coupler and two miniature microwave power dividers, wherein the external load directional coupler comprises a first input port, a straight-through port, a coupling port, an isolated port, a first input inductor, a broadside coupled strip line and three output inductors, the broadside coupled strip line is of an upper-lower-layer double helix structure, the straight-through port of the external load directional coupler is connected with an input port of the first microwave power divider, and the coupling port is connected with an input port of the second microwave power divider; and the two miniature microwave power dividers are each composed of a specific compact structure and a three-dimensional integrated structure, and are implemented by adopting a multi-layer low-temperature co-fired ceramic technology. The power of four paths of output signals of S-band miniature double-microwave external load orthogonal power divider is the same, the S-band miniature double-microwave external load orthogonal power divider has the advantages of being capable of generating quadrature phases, being easy to debug, having small insertion loss and the like, and is suitable for systems of corresponding microwave frequency bands, such as communication and satellite communication systems.

Description

technical field [0001] The invention relates to the technical field of power dividers, in particular to an S-band miniature double microwave external load orthogonal power divider. Background technique [0002] A power splitter (referred to as a power splitter) is an important microwave passive device. Power splitters are widely used in the field of wireless communications, mainly including microwave power amplification, linearization circuits, etc. From the mid-1950s to the 1960s, the world's first power splitter, called Wilkinson (Wilkinson) power splitter, was proposed in the world, which was realized by using the impedance transformation characteristics of a quarter-wavelength transmission line. With the rapid development of communication technology and the intensification of competition in the communication industry, new requirements have been put forward for the performance of Wilkinson power splitters. The traditional Wilkinson power splitter can only work in a sing...
