Abstract

The invention provides a multi-beam phased array chip. The multi-beam phased array chip comprises two first ports, eight shunt ports divided into two groups, each first port being connected with one group of four shunt ports through a balance differential circuit, and the signal loss coefficients between any two shunt ports in the eight shunt ports and the first ports correspondingly connected with the shunt ports being equal; eight phase shift circuits, wherein each phase shift circuit is only connected with one shunt port; four power dividers, wherein every two of the eight shunt ports in different groups are configured into a pair, and the four pairs of shunt ports are connected to the different power dividers through the phase shift circuits correspondingly connected with the four pairs of shunt ports respectively, and four second ports espectively connected to the different power dividers. In addition, the invention also provides a derivative structure based on the multi-beam phased array chip.

Description

technical field [0001] The invention relates to the field of circuit design of phased array antenna equipment, in particular to a multi-beam phased array chip, a receiver module and a transmitter module. Background technique [0002] In satellite communication, 5G communication and other application scenarios, the supporting antenna equipment needs to meet performance requirements such as multi-connection, high reliability, low latency and high bandwidth. Due to its fast electronic steering characteristics, phased array technology has become a solution to these problems. Core technologies for performance requirements. Phased array technology is to change the direction of the beam by controlling the phase of the unit. In order to ensure communication quality and low latency, a larger number of channels and more flexible beam steering are required, and it is usually necessary to set up a large-scale array with a large number of channels. Therefore, using multi-beam phased ar...
