Mm wave RF receiving/transmission device

Abstract

The invention comprises a transmitting device which comprises a millimeter wave harmonic up-converting module, a millimeter wave fixed amplitude-amplifying module and a millimeter wave signal modulation mixing module, and a receiving device which comprises a millimeter wave harmonic down-converting module and a millimeter wave fixed amplitude-amplifying module. The transmitting device can generate a single pulse modulation signal and a mixed pulse modulation signal, which are used for testing the indexing of receiving and transmitting parameters of a millimeter wave radar and complicate communication signals; the millimeter wave fixed amplitude-amplifying module of the transmitting device can improve the temperature stability of the output signal in amplitudes at the temperature ranging from -10 DEG C to 60 DEG C, and is convenient for conducting precise measurement on a radar receiver; the millimeter wave signal modulation mixing module can realize the analog of Doppler echo signals of the millimeter wave radar of different distances, and the front and back edges of the millimeter wave pulse generated by the millimeter wave signal modulation mixing module is less than 8ns, and the distortion never occurs in a narrow pulse of 100ns, and the millimeter wave signal modulation mixing module has more than 90dB of extremely dynamic numerical control precise attenuation; the receiving device can ensure that no distortion occurs in a dynamic testing range of 40dB, which is convenient for frequency measurement and pulse analysis; the transmitting device and the receiving device ofthe invention are easy to be realized, the costs of the components adopted are low, the size of the device is small, and the device is portable.

Description

technical field [0001] The invention belongs to the technical field of millimeter waves, in particular to a millimeter wave radio frequency transceiver. Background technique [0002] The seekers used for missile homing guidance mainly include photoelectric seekers, microwave seekers, and millimeter-wave seekers. Since the millimeter-wave seeker has the characteristics of high sensitivity, good resolution, and strong anti-interference performance, coupled with the millimeter-wave The guidance system is less affected by the plasma formed during the flight of the missile, and has the advantages of infrared and microwave at the same time. Therefore, the advanced missile terminal guidance abroad uses the millimeter wave precision guidance system. Research on millimeter-wave homing and guidance technology began in the late 1970s. Now Western countries not only cover the entire millimeter-wave band in terms of frequency, but also establish a complete research system from device to ...
