Abstract

This paper describes the design of the power amplifier (PA) for 5GHz WLAN transmitter. In order to realize the high power added efficiency (PAE), impedance matching circuit is calculated by using the load-pull method. In this case, output impedance of the PA is different from 50 ohm. Our proposed 5 GHz class-A PA matched to the impedance of maximum PAE is designed. This PA has 9.82 dB of gain and 20.2 % of PAE which is 1.8 point larger than that of 50 ohm impedance matched PA. This PA is fabricated on the 0.18 um CMOS technology and measured the RF properties.
