Abstract

A microwave frequency divider based on microwave photon technology, including: an optical domain down-conversion module, which converts the signal to be divided into an electrical domain signal with a reduced angular frequency under the action of an auxiliary microwave signal; electrical domain frequency division and frequency mixing A module, connected to the optical domain down-conversion module, for halving the angular frequency of the electrical domain signal, and mixing with the auxiliary microwave signal to generate a frequency-division signal of the signal to be divided by two; and the auxiliary microwave module , one end is connected to the optical domain down-conversion module, and the other end is connected to the electrical domain frequency division and frequency mixing module, which is used to provide adjustable Auxiliary microwave signals are used to alleviate technical problems such as the narrow frequency division bandwidth of the analog frequency divider in the prior art, the low operating frequency of the digital frequency divider, and the high power consumption when increasing the maximum operating frequency of the circuit.

Description

technical field [0001] The present disclosure relates to the field of microwave photonics, in particular to a microwave frequency divider based on microwave photonic technology. Background technique [0002] With the rapid development of wireless communication systems and other related fields, more wireless communication standard protocols have been widely used. In order to meet the requirements of different protocol standards, the research and design of multi-mode communication systems have attracted more and more attention. In a multi-mode communication system, the frequency synthesizer used to provide a standard reference frequency for high precision and stability standards is the most important point in the entire design. For the frequency synthesizer, the frequency divider is a very important key module, which is related to the highest frequency and frequency range that the frequency synthesizer can work.

Problems solved by technology

The analog frequency divider can work in a higher frequency band, but the frequency division bandwidth is narrow

The basic units that constitute a digital frequency divider are digital counters and flip-flops, which are simple in logic and structure, have a programmable frequency division ratio, and have a large operating frequency bandwidth, but their operating frequency is low, and the highest operating frequency of the circuit is improved. frequency, the power consumption of the circuit will also increase
