L-band minisize double microwave self-loading orthogonal power divider

Abstract

The present invention relates to an L-band minisize double microwave self-loading orthogonal power divider, comprising a directional coupler which is automatically connected with a matched load and two minisize microwave power dividers; wherein the directional coupler comprises input / output ports which are arranged in a surface mounting way, broadside coupled strip lines with double-spiral structures, and a matched load which is automatically connected at an isolated end thereof; the two minisize microwave power dividers are formed by a specific compact structure and a three-dimensional integration structure, and the above structures are all achieved through a multi-layer low temperature co-fired ceramic technology. The L-band minisize double microwave self-loading orthogonal power divider of the present invention has four output signals with the same power, and has the advantages of no need for external load, capacity of generating quadrature phase, easy debugging, light weight, small volume, high reliability, good electrical performance, good temperature stability, good batch consistency of electrical performance, low cost, batch production and so on, thus the L-band minisize double microwave self-loading orthogonal power divider is suitable for the occasions in which communication and satellite communication at a corresponding microwave frequency band have strict requirements for volume, electrical performance, temperature stability and reliability and corresponding systems.

Description

technical field [0001] The invention relates to a power divider, in particular to an L-band miniature double microwave self-loaded orthogonal power divider. Background technique [0002] Nowadays, whether it is military radar, electronic detection, electronic countermeasures, etc., or civilian mobile phone communication, TV, remote control, it is necessary to distribute and process electronic signals, which requires the use of an important microwave passive device—power divider ( Splitters). It is a microwave network that divides one signal into two or multiple signals. If it is used in reverse, it is a power combiner that synthesizes several signals into one signal. Now power splitters have been widely used in various in electronic equipment. [0003] With the rapid development of miniaturization of mobile communication, satellite communication and national defense electronic systems, high performance, low cost and miniaturization have become the development direction of ...
