A low complexity multistandard dual band wireless transceiver with integrated 24.7dBm 54% efficiency polar PA in a 0.13μm CMOS technology

This work presents a low complexity dual band wireless narrowband transceiver with integrated PAs. The digital-centric transceiver is suitable for IEEE 802.15.4 (ZigBee etc.), 802.15.4g SUN, Bluetooth, especially Bluetooth Low Energy and the upcoming 802.11ah sub-GHz WLAN, to enable future internet-of-things applications. The output power for the low band (800 to 960MHz) is 24.7dBm at 53.9% efficiency and for the high band (2.4GHz) 15.5dBm at 41.3% to allow high range applications without need of external PAs. The chip has been fabricated in a 0.13μm CMOS Technology.
