Abstract

The invention discloses a high-performance millimeter wave active vector synthesis phase shifter which sequentially comprises an input matching amplification circuit, a quadrature coupler, two inter-stage processing circuits, a vector synthesizer and an output matching circuit. The input matching amplification circuit is used for realizing impedance matching, direct current isolation and power amplification of an input signal; the orthogonal coupler is used for converting an input signal into an output signal with a phase difference of 90 degrees; the inter-stage processing circuit is used for carrying out amplification, noise reduction and phase adjustment on the two paths of signals with the phase difference of 90 degrees; the vector synthesizer is used for carrying out vector synthesis on the two paths of signals after interstage processing; and the output matching circuit is used for realizing impedance matching of the output signal. According to the invention, optimization of loss, phase error and gain error is realized, and the method also has the characteristics of large bandwidth, high precision and high integration level.

Description

technical field [0001] The invention relates to the field of phase shifters, in particular to a high-performance millimeter-wave active vector synthesis phase shifter. Background technique [0002] The phase shifter is the key module in the phased array radar. It is the main component to control and change the phase shift of the electromagnetic wave, and at the same time, it can realize the scanning and shaping of the beam. In recent years, with the increasing shortage of low-frequency spectrum resources, people's vision has gradually focused on the millimeter-wave frequency band (30GHz-300GHz), so the millimeter-wave frequency band phased array has become a hot research field at home and abroad. The millimeter-wave wireless communication system has the characteristics of large bandwidth and high maximum transmission power, and can realize high-speed wireless data communication with a rate of tens of Gbps. Therefore, it is of great significance to study millimeter-wave chip...
