This paper presents a novel dual-band class-E/F power amplifier (PA) with switchable output power. It is targeted to work in a BPSK/OOK transmitter in smart facility applications like an autarkic asset-tracking system based on small sensor nodes. The amplifier is fully-integrated and able to operate at both 434MHz and 868MHz without the need for additional inductors, making the design very area-efficient. The output power settings at 868MHz are controllable between -1.79dBm and -24.61dBm at 4.96mA and 1.43mA current consumption, respectively. The whole circuit including all inductors and the matching network in front of the antenna consumes only 0.9mm2 chip area and is fully integrated in a 180nm CMOS process together with a VCO and a PLL.
