Abstract:
An RF transmitter for a Wireless LAN device for enhancing an output linearity of the Wireless LAN device includes an RF processing unit for generating an RF signal, a voltage generator for generating a control voltage, a power amplifier coupled to the RF processing unit and driven by a bias, for amplifying power of the RF signal, and a low-pass filter coupled between the voltage generator and the power amplifier, for low-pass-filtering the control voltage to form the bias.
