A Frequency Synthesizer for Wireless Power Transfer at 5.8GHz and 61GHz

This paper presents the design of a frequency synthesizer for a millimeter wave localized wireless power transfer (WPT) radio frequency (RF) transmitter for Internet-of-Things (IoT) applications. The need for a convenient recharging method for the IoT devices has led to the emerging of the RF WPT system. This work is the first step of the design of a multi-band frequency synthesizer for RF based high-performance localized WPT transmitter designed at chip level. The presented system design supports the generation of a local oscillator (LO) signal for the modulation process at 5.8GHz and 61GHz. System level simulations of the behavioral model were carried out using MATLAB and Advanced Design System (ADS) programs.
