Abstract

The invention discloses a high distribution ratio reconfigurable power divider which comprises a metal ground plate and a dielectric substrate, the dielectric substrate being arranged on the metal ground plate, and also comprises a 3dB Wilkinson power divider, a 3dB branch wire coupler, a first pi-shaped equivalent transmission line and a second pi-shaped equivalent transmission line arranged on the dielectric substrate; the 3dB Wilkinson power divider is connected with the first pi-shaped equivalent transmission line and the second pi-shaped equivalent transmission line, and the first pi-shaped equivalent transmission line and the second pi-shaped equivalent transmission line are connected with the 3dB branch wire coupler. According to the power divider provided by the invention, high distribution ratio of output power can be achieved, and the distribution ratio is continuously reconfigurable in a large range.

Description

technical field [0001] The invention belongs to the technical field of radio frequency and microwave communication, and in particular relates to a reconfigurable power divider with a high distribution ratio. Main applications are antenna arrays, mixers, and real-time power distribution and synthesis. Background technique [0002] As an important part of the front end of the radio frequency circuit, the research and design of the power divider is getting more and more attention. The power splitter is referred to as a power splitter for short. In large-scale array antenna systems, phased array radar systems, and power combiners, multiple power splitters with different power distribution ratios are required. However, since the working principle of the radio frequency power divider determines the disadvantage of its large size, the application of multiple radio frequency power dividers will further increase the volume of the radio frequency front end and increase the production...
