Abstract :
This paper is the first demonstration of the validation results on the W-CDMA direct conversion receiver, based on the 3GPP definition. For the receiver, an even harmonic type direct conversion receiver is employed to achieve a high dynamic range. The proposed receiver has unique technical features of high sensitivity and selectivity, because the even order distortion can be suppressed with the monolithic diode pair of the mixer. This paper demonstrates experimental investigations on the receiver characteristics with the RAKE receiver, based on 3GPP specifications. The evaluation results which satisfy the required specifications are described. This paper clarifies the effectiveness of the proposed techniques for the third generation radio terminal
