Abstract

The invention discloses a broadband frequency extension device of a photoelectric oscillator, comprising: a narrow-band photoelectric oscillator, a frequency divider, a first phase-locked loop, and a second phase-locked loop, wherein the narrow-band photoelectric oscillator is connected with the frequency divider and the second phase-locked loop respectively. The input end of a phase-locked loop is connected; the input end of the second phase-locked loop is connected with the output end of the first phase-locked loop and the frequency divider respectively; Output after phase-locked loop frequency conversion. The invention solves the problem that the phase noise of the reference source of traditional frequency synthesis cannot meet the requirement of mass transmission; through the multi-ring frequency expansion technology, it solves the problem that the output frequency of the photoelectric oscillator is narrow and cannot meet the calibration requirement of broadband.

Description

technical field [0001] The invention relates to the field of optoelectronics. More specifically, it relates to a broadband frequency extension device of an optoelectronic oscillator. Background technique [0002] In the microwave and millimeter wave frequency range, the low phase noise reference sources currently on the market mainly include the imported HP8663A / B, E8257D and SMA / B series, etc. The components of these reference sources mainly include low-noise time-base links, harmonic Generator, baseband signal, intermediate frequency unit, up-conversion unit, down-conversion unit and display and control system. These microwave and millimeter wave reference sources all adopt traditional frequency synthesis schemes, the most notable disadvantage of which is that the phase noise level drops significantly as the output frequency increases. Moreover, with the improvement of the development level of the phase noise of the microwave and millimeter wave source to be tested, the ...
