5G communication frequency source based on superconducting material

Abstract

The invention relates to a 5G communication frequency source based on a superconducting material, which belongs to the field of microwave circuit design and comprises a first oscillator module and a second oscillator module which are the same, and a dielectric resonator module is connected in series between the first oscillator module and the second oscillator module; the output ends of the two oscillator modules are synthesized into total output through the power divider module made of superconducting materials, and the dielectric resonator module has 180-degree phase shift, so that a 180-degree phase difference exists between fundamental wave signals generated by the two oscillators. The design of the power divider module is realized by using a high-temperature superconducting structure,the second harmonic of the signal generated by the oscillator module is output, fundamental wave and higher harmonic signals are suppressed, and the phase noise is improved. The 5G communication frequency source is simple to process, flexible and adjustable, simple in structure and easy to integrate.

Description

technical field [0001] The invention belongs to the field of microwave circuit design, and relates to a millimeter-wave frequency source for 5G communication based on a superconducting material structure. Background technique [0002] In systems that transmit time or frequency signals, a highly stable frequency source is critical for proper system operation. Frequency stability can be divided into long-term stability and short-term stability. Long-term stability is related to factors such as ambient temperature and component aging; short-term stability depends on the phase noise coefficient of the system. In order to obtain higher stability, it is necessary to improve the anti-interference ability of the circuit and the parameter level of the system phase noise. [0003] Due to the limited maximum operating frequency of active devices, the operating frequency of common FETs can only reach about 20GHz. When the required oscillation frequency exceeds this range, the frequency...

Problems solved by technology

[0004] At present, in the domestic and foreign research in this direction, the working environment temperature range of the power divider is generally required to be -10°C to 40°C or -30°C to 50°C, and the higher power divider is required to be able to operate at -45°C to 80°C Working within the temperature range, but for some alpine regions, the working temperature of the current power divider is difficult to meet the requirements, which will greatly affect the stability of the frequency source
