Abstract

The invention discloses a hybrid branch line coupler capable of realizing frequency and power division ratio reconstruction at the same time. Based on the branch line structure, the frequency and power division ratio can be reconfigured, which not only realizes the function of the power divider but also realizes the working frequency Adjustable, very suitable for the application of modern wireless communication systems; compared with the existing technology, by loading a varactor diode on the branch line coupler, any power ratio and any center frequency output can be realized, and the overall structure is simple, It can realize miniaturization and is easy to integrate; in addition, because it uses a planar microstrip structure, it is easy to manufacture and low in cost; because the output frequency is adjustable, it can realize communication in a wider broadband range. Therefore, the present invention is reasonable in design and simple in structure, can meet the requirements for output power variation of output signals, and can work in multiple communication frequency bands, which is beneficial to improving the overall performance of the communication system.

Description

technical field

[0001] The invention relates to the field of microwave communication, in particular to a hybrid branch line coupler which realizes frequency and power division ratio reconstruction at the same time. Background technique

[0002] With the rapid development of 5G technology and multi-standard communication systems, in order to meet its needs, the performance requirements of radio frequency devices working in the microwave and millimeter wave bands are getting higher and higher. The coupler is an indispensable component in radio frequency devices. It is a directional power distribution element that can distribute power from the forward wave of the main transmission system to the coupling end and the through end in different proportions. Couplers are widely used in feeder networks of base station systems, balanced amplifiers, radar systems, balanced mixers, power gain control devices, antenna array systems, and phased array radar systems. Previous research has b...
