Abstract

The invention provides an ultra-wideband receiver, and the receiver comprises a radio frequency balun for converting a single-ended radio frequency signal into a differential radio frequency signal; an ultra wide band frequency conversion assembly which performs frequency conversion on the differential radio frequency signal based on a local oscillator signal of a preset frequency band and outputs a differential intermediate frequency signal; an intermediate-frequency balun which is connected to the output end of the ultra-wideband frequency conversion assembly and converts the differential intermediate-frequency signal into a single-ended intermediate-frequency signal; and an intermediate-frequency signal processing module which is connected to the output end of the intermediate-frequency balun and is used for processing the single-ended intermediate-frequency signal. According to the invention, the size of the cross-band broadband receiver can be effectively reduced, the number of equipment for building the broadband receiver is reduced, the link loss and power consumption of the broadband receiver are reduced, and the power stability during long-term work is greatly improved through an automatic gain compensation mode, so the receiver has the characteristic of being directly used for system integration, and the defects in the prior art are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of high-frequency electronics, in particular to an ultra-wideband receiver from X-band to V-band. Background technique [0002] The main function of the receiver is to amplify and process the required echo reflected back after transmission, and to filter the echo in a way to obtain the maximum discrimination rate between the useful echo and the useless interference, which is widely used in signal Reception, signal processing and identification, signal measurement and testing and other important electronic technology fields, which convert the electromagnetic wave signal received by the antenna into an electromagnetic signal acceptable to the digital signal processing circuit through the frequency conversion device, including continuous wave and various pulse signal etc. With the continuous development of the integrated circuit field and the continuous improvement of the frequency band of the existing electro...
