The power splitter is an important device for applications such as microwave signal separation and array antenna feeding. After the emergence of the right and left hand transmission lines, most of the miniaturized power splitters are designed by utilizing the miniaturization characteristics of the left and right hand transmission lines. This paper summarizes the application of left and right hand transmission lines in the power splitter, and analyzes the advantages and disadvantages of different implementation methods.

Introduction

A power splitter is a device commonly used in microwave passive systems that can distribute the energy of one input signal into multiple signal energy according to engineering requirements. Can be applied to phase shifters, power adapters, duplexers T-junctions and porous slot couplers, and can also be used for the distribution of IF signals in satellite receivers connected to antennas; in wireless communications, single solid-state devices The output power is limited as the frequency increases, and another method of using the power combiner can remedy this limitation. The reverse use of the power splitter can simultaneously combine several scattered energies to achieve high power output. There are many types of power splitters. According to the materials, common microwave power split devices have microstrip power split, waveguide splitter and substrate waveguide splitter; among them, the microstrip splitter is small in size, compact in structure and cost-effective. However, its bandwidth is narrow, power capacity is small, and insertion loss is large.
