Problems solved by technology

In comparison, the ferrite phase shifter has small power capacity, small insertion loss, and large phase shift, but requires complex control circuits and large volume and weight
Semiconductor PIN diode is the earliest developed and most widely used digital phase shifter. This type of phase shifter can be controlled by digital signals and has a fast working speed, but it consumes a lot of power and has a small power capacity. Strong performance dependency

Abstract

The invention provides a transmission type miniaturized 90-DEG phase shifter. The transmission type miniaturized 90-DEG phase shifter includes a main microstrip line and a choking structure, wherein the main microstrip line includes a dielectric layer board, a main microstrip transmission line and a metal backing plate, the main microstrip transmission line is connected with one side of the dielectric layer board, the metal backing plate is connected with the other side of the dielectric layer board, two PIN diodes are connected in parallel between the main microstrip transmission line and themetal backing plate, one end of the choking structure is connected with the main microstrip transmission line, the other end of the choking structure is connected with a positive pole of an externalDC stabilized power supply, and the metal backing plate is connected with a negative pole of the external DC stabilized power supply. The transmission type miniaturized 90-DEG phase shifter is advantaged in that output phase difference can be 90 DEG, a phase shift error is less than 5 DEG, transmission amplitude difference is small, the regulatory response time is short, energy consumption is low,power consumption is less than 1mW, the state switching speed can reach the ns level, the phase shifter can be combined with digital signal processing and phased array radar communication systems, etc., the phase shifter has a very high application value in the military and civilian fields, and the phase shifter is applied to the technical field of a phase shifter.

Description

technical field [0001] The invention relates to the technical field of phase shifters, in particular to a transmission type miniaturized 90° phase shifter. Background technique [0002] As a device that can control the phase change of the signal, the phase shifter is one of the important modules commonly used in the field of microwave engineering. It is widely used in communication, radar systems, instrumentation and other fields, especially in phased array radar, phase modulation communication system and intelligent wireless mobile communication system. With the development of the phased array antenna system, based on the performance requirements of the radar system in terms of accuracy, sensitivity, multi-function, multi-target, and weight and volume, the performance requirements of the phase shifter as the core component of the antenna feed network are increasing. promote. [0003] The traditional phased array is a scanning antenna composed of many transmitting / receivin...
