  This research was to design a 2.4 GHz class E Power Amplifier (PA) for health
care, with 0.18um Semiconductor Manufacturing International Corporation CMOS
technology by using Cadence software. And also RF switch was designed at
cadence software with power Jazz 180nm SOI process. The ultimate goal for such
application is to reach high performance and low cost, and between high
performance and low power consumption design. This paper introduces the design
of a 2.4GHz class E power amplifier and RF switch design. PA consists of
cascade stage with negative capacitance. This power amplifier can transmit
16dBm output power to a 50{\Omega} load. The performance of the power amplifier
and switch meet the specification requirements of the desired.
