摘要

In this paper, a broadband CSCMR with pintable PCB is designed. This wireless power transfer system is able to achieve 20 MHz bandwidth at the operating frequency of 115 MHz, while maintaining around 80% power transfer efficiency. Utilizing this large bandwidth, high data rate digital communication through the same link is also achieved using backscatter modulation. The whole system is able to deliver 20% power to a 47 Omega load with a 41% power conversion efficiency rectifier, while receiving 2 Mbps data from the data input.
