Abstract

This paper describes a 802.15.6 compliant 23602484MHz multiband transmitter that digitally multiplexes the appropriate phases from an 800MHz poly-phase filter output to generate π/4 DQPSK signals at 2.4GHz. Modulation at 1/3 rd the RF frequency reduces the transmitter power consumption and enables channel selection using a PLL running at 800MHz. The prototype transmitter consumes 2.4mW while delivering -10dBm RF power at the TX output resulting in an energy efficiency of 2.5nJ/bit at 1.2Mbps. The measured RMS EVM for π/4 DQPSK modulation is 3.21%.
