Radio frequency wideband frequency agility frequency source

Abstract

The application discloses a radio frequency wideband frequency agility frequency source. The radio frequency wideband frequency agility frequency source comprises a frequency reference module, a baseband module, a local oscillator module and a frequency conversion module; the frequency reference module is used to output a 1000MHz reference signal to the baseband module and output a 1000MHz excitation signal to the local oscillator module; the baseband module is used to output a 200MHz to 400MHz baseband signal to the frequency conversion module; the local oscillator module is used to output six point frequency signals to the frequency conversion module, wherein the output frequency range of the point frequency signals is 10GHz to 20GHz and the frequency interval is 2GHz; and the frequencyconversion module is used to extend the frequency of the 200MHz to 400MHz baseband signal, so that the output signal frequency covers 1.25-20GHz. Compared with the traditional frequency source, the scheme disclosed by the invention has better indexes and a smaller structure size.

Description

technical field

[0001] The present application relates to the field of microwave technology, in particular to a radio frequency source. Background technique

[0002] As an important part of the electronic system, the frequency source is widely used in technical fields such as communication, electronic warfare, radar detection, guidance and control, navigation and positioning, measurement and testing. In addition to ground equipment, its application environment covers missiles, satellites , aircraft, space and many other special applications. With the continuous development of various high-tech technologies such as micro-nano satellites, light unmanned aerial vehicles, miniature interceptors, and high-efficiency space equipment, the requirements for miniaturization and even miniaturization of frequency sources have become increasingly prominent. Energy consumption has become a bottleneck that restricts the full play of the new generation of technology, and technological inno...
