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

Embodiment Construction

[0016] refer to figure 1 . figure 1 The best embodiment of an all-in-one transceiver front-end for the millimeter-wave frequency band is described. The described transmit-receive front-end integrated in the millimeter-wave frequency band includes two functional modes of the integrated seeker and fuze, as well as the radio frequency transmission branch with the transceiver control function and the radio frequency reception branch under the protection of the limiter. The radio frequency transmitting branch and the radio frequency receiving branch of the transceiver front-end share an external local oscillator input signal through a power divider.

[0017] In the radio frequency transmission branch, the transmission intermediate frequency input signal and the local oscillator signal are mixed by a mixer to achieve superheterodyne upmixing, and the transmission signal is filtered and amplified by a bandpass filter and a drive amplifier, and then the fuze mode driver is used to re...

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...
