Abstract
This paper reports the design and simulation results of a 433 MHz Power Amplifier (PA) which is designed in a 0.5 /spl mu/m CMOS technology and can provide variable gain modes. The PA consists of a driver and an output stage, and the gain is adjustable using digital codes. In this paper, 16.5 dB and 3.5 dB gain modes are chosen. This amplifier matches a 50 ohm load and provides 20 mW of output power at 432-434 MHz from a 3 V supply. The overall power efficiency is 30%.
