Abstract
This work presents the RF performance and effect of phase and amplitude error calibration in a smart antenna system based on WCDMA. We focus on the design and implementation of the RF subsystem and suggest a phase and amplitude error calibration method for the smart antenna system. The RF subsystem consists of an 8-element array antenna, RF front-end, high power amplifier, RF transceiver, digital IF transceiver, and the digital calibration unit which can support switched and adaptive beamforming simultaneously. Experimental results are shown for RF performance and we propose phase and amplitude error calibration at the analog part which can mitigate the amount of DSP in the digital calibration unit.
