Theory And Experiments

Injection-locking technique is receiving increasing interest in industrial applications, which is especially suitable for smart antenna array, but relative experiments are complicated. The article focuses on the theory and experiment of the technique. Firstly, section 2 reviews the theory of injection-locking technique, and summarizes two useful conclusions on injection-locking bandwidth and phase difference adjusting bound of the phenomena. Secondly, section 3 describes experiments using commercial microwave integrated circuit (MMIC) voltage controlled oscillator (VCO), which is reduces the experimental conditions. Experiments results perform very well.

A 5G mm-wave monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) is presented in this paper. It is designed on GaAs substrate and with 0.25 µm-pHEMT technology from UMS foundry and it is based on pHEMT varactors in order to achieve a very small chip size. A 0dBm-output power over the entire tuning range from 27.67 GHz to 28.91 GHz, a phase noise of -96.274 dBc/Hz and -116.24 dBc/Hz at 1 and 10 MHz offset frequency from the carrier respectively are obtained on simulation. A power consumption of 111 mW is obtained for a chip size of 0.268 mm2. According to our knowledge, this circuit occupies the smallest surface area compared to pHEMTs oscillators published in the literature.
