Multi-beam phased array chip, receiver module and transmitter module

Abstract

The present invention provides a multi-beam phased array chip, the multi-beam phased array chip includes: two first ports; eight shunt ports divided into two groups, each of the first ports passes through a balanced differential circuit It is connected to a group of four branch ports, and the signal loss coefficient between any two branch ports in the eight branch ports and the first port correspondingly connected thereto is equal; eight phase shifting circuits , each of the phase-shifting circuits is only connected to one of the branch ports; four power dividers, the two of the branch ports of different groups in the eight branch ports are configured as a pair, and the four pairs of the branch ports are configured as a pair. The branching ports are respectively connected to different power splitters through the phase-shifting circuits correspondingly connected thereto; the four second ports are respectively connected to different power splitters. In addition, the present invention also provides a derivative structure based on the above-mentioned 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...
