Abstract

In this paper, a reconfigurable class E oscillator/rectifier, based on an Enhancement-mode Pseudomorphic High Electron Mobility Transistor (E-pHEMT), is proposed. Using high Q lumped elements for implementing the desired terminations at drain side, as well as for the feedback/phase shifting network, the same circuit can be used either as a DC-to-RF inverter for efficient signal transmission, or as a RF-to-DC rectifier for wireless powering. Designed at the 960 MHz frequency band, an efficiency value of 76% has been measured in the oscillating mode for an output power of 17.5 dBm, with a -127 dBc/Hz phase noise figure at 1 MHz frequency offset. A 79.6% peak efficiency value has been obtained when operated as rectifier.
