Ultra-wideband one-to-four power divider

Abstract

The invention discloses an ultra-wideband one-to-four power divider. Three one-to-two power dividers are connected together in a cascading manner, and meanwhile, a circuit form of a multilayer board is adopted, so that the design of a circuit structure is optimized, and the microwave performance and the producibility of the power divider are improved. The working frequency of the power divider designed by the invention is 6-18GHz. It can be known through simulation software verification that the return loss is superior to -13dBm, the insertion loss is superior to -7dBm, and the isolation degree is superior to -12dBm. A processing object verification result shows that a theoretical simulation result is basically consistent with an experimental test, and the feasibility of the design methodis proved.

Description

Technical field [0001] The invention belongs to the field of communication, and specifically, is an ultra-wideband one-to-four power divider. Background technique [0002] The power splitter is the main component in the microwave system that realizes signal distribution from one port to port or synthesis from N port to port. It is widely used in microwave equipment such as phased array radar and multi-channel relay communication machine. The core requirements of contemporary high-efficiency systems for power splitters are: broadband, small size, low insertion loss and high isolation between ports. Therefore, the use of miniaturization solutions to design traditional broadband power splitters and the use of new transmission lines to design high-performance broadband miniaturized power splitters have become important research content of passive devices. [0003] Ultra-wideband means that the relative bandwidth of the communication frequency band is greater than 25%. In order to ach...
