Abstract

A 2GHz band even harmonic type direct conversion receiver (EH-DCR) is proposed for the W-CDMA mobile terminal. Because of the well-matched anti-parallel diode pair used in proposed EH-DCR, the proposed receiver can reduce even order mixing products that degrade sensitivity characteristics. Also the proposed EH-DCR can achieve low current consumption with a passive mixer approach. In this paper, the overall receiver with a RF block, an analog baseband IC (ABB-IC) and a demodulator is demonstrated to indicate effectiveness on the proposed RF architecture. Described evaluation results indicate high instantaneous dynamic range with high sensitivity.
