Millimeter wave band fuse and control integrated transmitting-receiving front end

Abstract

The invention provides a millimeter wave band fuse and control integrated transmitting-receiving front end and aims at providing a fuse and control integrated transmitting-receiving front end which has high transmitting-receiving switchover speed, great modulation depth, short receiving recovery time and a detection blind zone of less than 15m. The front end is implemented by the following technical scheme of: transmitting an intermediate frequency input signal and a local oscillation signal for superheterodyne mixing via a mixer in a radio frequency emission branch, controlling an absorption switch to achieve conversion of a seeker mode and a fuse mode by using a fuse mode driver after through a band-pass filter and a driving amplifier, introducing high-speed radio frequency switches before and after a power amplifier, achieving transmitting-receiving switchover via a radio frequency switch driver, introducing an amplitude limiter at the front end of a radio frequency receiving branch, keeping a receiving channel in a linear state, and subsequently, allowing a receiving signal to sequentially pass through a low-noise amplifier, the band-pass filter and the mixer to enter an intermediate frequency output channel.

Description

technical field [0001] The present invention relates to a millimeter-wave frequency band lead-guiding integrated transceiver front-end architecture that can be widely used in communication, radar, and various fields, and is especially suitable for a millimeter-wave frequency band radar seeker and proximity fuze composite integrated transceiver front-end design. Background technique [0002] In mmWave systems, the transceiver front-end plays a key role in system performance. The theoretical design of the millimeter-wave transceiver front-end passive circuit mainly involves millimeter-wave bandpass filters and waveguide-microstrip transitions, mainly including amplifiers, mixers and switches. The millimeter wave front-end system is mainly composed of transmitter, receiver, signal source, baseband signal processor and various interface devices. The millimeter-wave transceiver front-end is to integrate the millimeter-wave transmitting module and receiving module into a millime...

Problems solved by technology

However, under these systems, due to complex analysis algorithms, many external environmental factors, and low time-domain control accuracy, the minimum detection distance and detection accuracy of the fuze function are far lower than those of the millimeter-wave narrow pulse system.

So far, there have been no relevant reports on the introduction and manufacture of integrated transceiver front-ends suitable for millimeter-wave pulse systems
