Background technique [0002] Millimeter-wave communication systems are favored by academia and industry due to the advantages of fast communication rates and high availability. Taking the fifth generation mobile communication (5G) as an example, various countries have deployed multiple developable frequency bands. For example, the Ministry of Industry and Information Technology of China has approved the 24.75-27.5GHz and 37-42.5GHz frequency bands for 5G research and development; the US Federal Communications Commission Three main communication frequency bands 28 (27.5-28.35GHz), 37 (37-38.6GHz) and 39 (38.6-40GHz) have been opened. Therefore, if a radio frequency communication system covering multiple frequency bands ...

Problems solved by technology

However, the bandwidth and phase noise of the frequency source in the RF front-end limit the development of the entire communication system, and new technologies are urgently needed to expand the bandwidth on the premise of ensuring the output phase noise of the frequency source

[0003] At present, most frequency source systems directly use the output signal of a high-frequency, broadband phase-locked loop (PLL) as the local oscillator source. However, in this mode, the design of an ultra-wideband VCO (voltage-controlled oscillator) faces challenges. Efficiency and stability cannot be balanced, and often cannot meet the requirements of 5G communication

[0004] Another commonly used mode is to use a broadband frequency multiplier to multiply the frequency of the signal output by the phase-locked loop (PLL). Compared with the previous one, the output bandwidth of the voltage-controlled oscillator (VCO) is further reduced, but for The design of broadband frequency multiplier poses challenges, and it is difficult to meet the broadband requirements of 24.75-42.5GHz with a single frequency multiplication mode

[0005] In addition, the application of a multi-mode frequency multiplier can minimize the output bandwidth of the voltage-controlled oscillator (VCO) and optimize the phase noise of the phase-locked loop (PLL) output. However, the traditional multi-mode frequency multiplier is accompanied by multi-port output. The circuits between different modes are independent of each other, which is equivalent to integrating multiple frequency multiplier chips inside the system, occupying a large chip area and increasing power consumption

At the same time, multi-port is not conducive to the cascading of back-end circuits
