Abstract

The invention relates to a distributive correlator. The circuit structure comprises a power divider and three lambda / 4 wave couplers, a port 1 and a port 2 are used as input ports, and a port 3 to a port 6 are used as output ports. The couplers are realized by open short circuits. The distributive correlator effectively solves the problem that correlated operation mistakes are made during use of most integrated devices. The circuit structure enhances temperature insensitivity of a resistor and is good in applicability and high in stability. Meanwhile, the correlator with six ports can filter at different frequency bands, and can be widely applied to systems demanding correlators.

Description

technical field [0001] The invention relates to a correlator, in particular to a distributed six-port correlator, which belongs to the field of electronics and communication. Background technique [0002] With the development of microwave and millimeter wave communication, radar and other systems, especially the development of mobile handheld wireless communication terminals, satellite mobile communication terminals, military and civilian multi-mode multi-channel communication system terminals, the requirements for related devices in the system are becoming more and more stringent. Among them, many lumped components caused system-related calculation errors due to poor correlator performance, which slowed down the development of terminals for a while. In recent years, many researchers at home and abroad have focused on solving this problem and proposed a series of solutions, such as RLC and active related circuits and transmission line related circuits, which have promoted th...
