Abstract

The proposed direct conversion scheme combined with a multi-phase sampling fractional-N prescaler offers solutions to problems of a direct conversion transmitter and receiver. In the experimental results, the transmitter shows 0 dBm maximum output power with 38 dB ACPR at 0.5 BW, 50 dB dynamic range, and 363 mW power consumption. The receiver shows -115.4 dBm sensitivity, 4.0 dB noise figure, and 80 dB dynamic range with 396 mW power consumption.
