2.4GHZ Class F Power Amplifier for Wireless Medical Sensor Network

The objective of this research was to design a 2.4 GHz class F Power Amplifier (PA), with 0.18um Semiconductor Manufacturing International Corporation (SMIC) CMOS technology by using Cadence software, for sensor network, especially for health care. The ultimate goal for such application is to minimize the trade-offs between performance and cost, and between performance and low power consumption design. This power amplifier can transmit 18dBm output power to a 50Ω load. The power added efficiency is 46% at 1dB compression point and the power gain is 18dB, the total power consumption is 2.8W. The performance of the power amplifier meets the specification requirements of the desired.
