Abstract

The invention relates to an S-band microwave quadrature power divider which comprises a microwave power divider and two directional couplers. The microwave power divider is composed of a specific compact structure and a three-dimensional integrated structure. The directional coupler comprises a surface-mounted input / output port and double-helix structured broadside coupled striplines. The above structures are realized by a multilayer low-temperature co-fired ceramics technology. According to the invention, four routes have the same output signal power. The power divider can generate quadrature phase, is easy to debug, is light in weight, has high reliability, good electrical property, good temperature stability and good electrical property batch consistency, is low-cost, can be used for mass production and is suitable for occasions and corresponding systems of corresponding microwave frequency band communication, satellite communications and the like which have strict requirements on volume, electrical property, temperature stability and reliability.

Description

technical field [0001] The invention relates to a power splitter, in particular to an S-band microwave orthogonal power splitter. 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 the microwave / radio frequen...
