2.4 GHz WLAN InGaP/GaAs Power Amplifier With Temperature Compensation Technique

Recently, the Wireless Local Area Network (WLAN) market has grown rapidly due to the increasing demand for high data rates. It requires a highly linear Power Amplifier (PA) because of a high peak-to-average ratio. The linearity of an 802.11g PA is generally evaluated through Error Vector Magnitude (EVM) because information is carried on both magnitude and phase of a signal. Therefore, EVM is a key parameter for 802.11g PA development along with gain and efficiency.
