Optimum Design of the Adaptive Predistortion Power Amplifier For WCDMA RF Subsystem

摘要：

In this paper, an adaptive predistortion RF power amplifier for repeater subsystem is introduced. With an optimum gate bias voltage of the power amplifier, ACPRs of 12 and 13.5dB are improved for the cases of the upper and lower channels. It delivers a Pout of 33dBm with an ACPR of -50dBc in the implementation. The characteristic of the adaptive predistortion RF power amplifier with two loops performed excellent under various conditions, such as vary input power levels, temperature, and operating frequency channels.
