Planar arbitrary multipath power divider and synthesizer

Abstract

The invention discloses a planar arbitrary multi-path power divider and synthesizer. The planar arbitrary multi-path power divider and synthesizer comprises an upper dielectric plate, a lower dielectric plate attached to the upper dielectric plate, and a GND arranged at one end of the lower dielectric plate, a center position connected with the lower dielectric plate is arranged in the middle of the upper dielectric plate, an input port is arranged at the center position, output ports are evenly and fixedly connected to the periphery of the upper dielectric plate, and a plurality of upper metal layer microstrip transmission lines are arranged on the upper dielectric plate around the center position. Each upper metal layer microstrip transmission line is provided with a first metalized through hole. A connecting metal layer is arranged at the center of the lower dielectric plate, a plurality of second metalized through holes are uniformly formed in the connecting metal layer, and a plurality of lower metal layer microstrip transmission lines are uniformly arranged around the connecting metal layer. According to the power divider, power distribution and synthesis of any path can be realized at will, and the power divider has excellent performance while the size is compact and miniaturization of a microwave system is easy to realize.

Description

technical field [0001] The invention relates to the technical field of microwave components, in particular to a planar arbitrary multi-channel power divider and combiner. Background technique [0002] The full name of the power divider / synthesizer is the power divider / synthesizer. Its function is to divide the energy of one input signal equally or unequally into multiple signals, so that a signal with lower energy can be obtained. At the same time, it can also be used in reverse, which is called power A synthesizer, which combines the energy of multiple signals into one output, and can obtain a signal with greater energy. The power divider plays a very important role in modern communication technology and is an indispensable part of the radio frequency circuit. It is widely used in antenna array feeding systems and power amplifiers. [0003] At present, there are mainly Wilkinson power dividers and Gysel power dividers. Wilkinson has a simple structure and is widely used in...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly Wilkinson power dividers and Gysel power dividers. Wilkinson has a simple structure and is widely used in transmitting front-end modules, but it cannot directly divide multiple channels. If multiple channels are required, multi-stage cascading is required. can only be 2 n circuit (n≥1), the degree of freedom is low, and when making multiple channels, the isolation resistor needs to be bridged, which is not easy to process; although the Gysel power divider can be directly divided into more than one, but the frequency band is narrow, it has a three-dimensional structure, and the volume is relatively small. Big, not easy to miniaturize
