The complementary reconfigurable power divider based on a reflective phase shifter has the advantages of being good in classification effect and small in annotation training set requirement.

Description

technical field [0001] The invention relates to the technical field of radio frequency and microwave communication, in particular to a complementary reconfigurable power splitter based on a reflective phase shifter. Background technique [0002] As an important device of the RF front-end circuit, the research and design of the power divider (hereinafter referred to as "power divider") has received a lot of attention from academia and industry, especially in large-scale array antenna systems, phased array radar systems and power In the field of synthesizer applications, the performance of power dividers directly determines the performance of the entire system. Due to the disadvantages of large device sizes in traditional RF power dividers, cascading multiple RF power dividers will further increase the overall RF front-end circuit. Size and production cost, while the power distribution ratio reconfigurable power divider can replace multiple devices with one device, which can n...

Problems solved by technology

[0003] At present, the research on the distribution ratio reconfigurable power divider is mainly concentrated in the field of discrete reconfigurable power distribution ratio. Due to the complex structure and discrete distribution ratio, the application is limited, while the traditional distribution ratio continuous reconfigurable power Due to the low adjustable range and non-adjustable phase of the device, the practicability is low. Therefore, the present invention designs a complementary reconfigurable power splitter based on a reflective phase shifter by improving and optimizing its design method and structural parameters. device, which realizes the reconfigurable function of distribution ratio and phase difference at the same time
