Abstract

In this paper we present a reconfigurable Class-E Power Amplifier (PA) whose operation frequency covers all uplink bands of GSM standard. We describe the circuit design strategy to reconfigure PA operation frequency maximizing the efficiency. Two dies, manufactured using CMOS and MEMS technologies, are assembled through bondwires in a SiP fashion. Prototypes deliver 20dBm output power with 38% and 26% drain efficiencies at lower and upper bands, respectively. MEMS technological issues degrading performance are also discussed.
