Abstract

The invention discloses a broadband injection locking frequency multiplier, which adopts a double-injection structure and comprises two harmonic generators and an injection locking oscillator. The harmonic generators are used for generating harmonic signals of two or more times, the injection locking oscillator is used for locking the harmonic signals generated by the harmonic generators, and thetwo harmonic generators and the injection locking oscillator are coupled and connected through transformers composed of inductors arranged in the two harmonic generators and the injection locking oscillator. The two harmonic generators convert input fundamental wave signals into two paths of harmonic signals, and then the two paths of harmonic signals are respectively coupled to the injection locking oscillator through the transformer to realize frequency multiplication. Compared with a traditional structure, the broadband injection locking frequency multiplier still has a wide locking range when the input power is small, and has the advantages of being ultra-wide in broadband, low in input sensitivity, low in power consumption, high in integration level and the like.

Description

technical field

[0001] The invention relates to a broadband injection-locked frequency multiplier, which belongs to the technical field of radio frequency and analog integrated circuits of microelectronics and solid electronics. Background technique

[0002] In recent years, wireless communication technology has developed rapidly, and the development of millimeter wave and terahertz frequency bands has become more and more popular. The design of wireless transceivers with high integration, high bandwidth and low power consumption has become very important. Wireless transceiver systems rely on reliable IF signals for better system performance. As an important part of the intermediate frequency signal generation chain, the frequency multiplier completes the function of multiplying the fundamental frequency.

[0003] In the use of intermediate frequency signals, it is necessary to frequently take frequency multiplication measures to improve system performance. In a superheter...
