Abstract

The invention discloses a quartering microstrip power divider. The quartering microstrip power divider comprises a shell (1), a signal input and output port group (2) and a power divider assembly (3), wherein the power divider assembly (3) adopts a multi-branch snakelike structure to output power distribution signals and has a plurality of power dividers in topological connection. On the basis of Wilkinson power divider topology, five-branch snakelike routing is adopted to broaden the frequency band, so that the frequency band is expanded to DC-6G; the length of each branch is reduced to be smaller than lambda / 4, and the coupling distance of each branch is shortened as far as possible to reduce the size; through measures of adjusting characteristic impedance of each branch and the like, microstrip isolation is improved, the size and performance of the coupler are enabled to be optimal, and the requirement of miniaturization design and the requirement of isolation are met. The invention aims at solving the technical problem that the miniaturization requirement of a traditional Wilkinson power divider is not enough in the using environment with higher space requirement in the prior art.

Description

technical field [0001] The invention relates to the field of microstrip power dividers, in particular to a quartered microstrip power divider. Background technique [0002] A power splitter is a multi-port network device that can divide the input signal into equal or unequal power distribution. It is widely used in antenna beamforming and wireless multi-channel communication systems. With the rapid development of wireless communication technology and communication equipment coverage, as well as the diversification of deployment scenarios, power splitters, as an important passive device, have been increasingly widely researched and applied. Among them, broadbandization and miniaturization are the hotspots of research. [0003] For the power splitter, its design requirements mainly include: small port standing wave coefficient, small in-band fluctuation, high port isolation, low transmission loss and good phase consistency, and the circuit form should be simple and easy to m...
