摘要：
A 17GHz low power radio front-end is presented. Low-power operation is based on minimization of energy[bit, the design metric for low-power radios. Increasing the data rate while reducing the receiver turn-on time is proposed as a method of improving energy efficiency. Circuit design of prototype receiver and transmitter front ends for a 17GHz ultra low-power radio are presented and discussed. The power gain of the LNA is 12dB with a minimum noise figure of 3.25dB. Conversion gain of the RF chain is 30dB at DC, the measured IIP3 of the Rx chain is 26.3dBm whereas the maximum saturated output power of the PA is about 5dBm. The total, measured power consumption is 17.5mW (@2.5 supply) in the received mode and 16mW (@ 2.5 supply) in the transmit mode.
