Abstract

An experimental 2.4GHz CMOS radio composed of RF and digital circuits for the low power and low rate IEEE802.15.4 WPAN is reported, consuming 21mW in receiver and 30mW in transmitter. The RF design focus is to maximize linearity per power using linearization methods, which lead an order of improvement in LNA/Mixer IIP3/power performance. Chip-on-PCB technology allows implementation of small size radio at very low cost, which also provides 3dBi gain patch antenna and high Q (>50) inductors. This receiver has -82dBm sensitivity and -4dBm IIP3.1.
