Abstract

In this paper, we measured the efficiency of the receiver for 5.8GHz Microwave Smartphone Charging. We have designed and fabricated 1W and 2W power amplifier, respectively. A 1W power amplifier used a TC3531 power device of TRANSCOM Inc. In addition, a 2W power amplifier using the two TC3531 devices was constructed with divider and combiner. We used the Wilkinson divider theory for divider and combiner. The voltage was measured using the 1W and 2W power amplifier and integrated receivers to the distance of 50cm.
