Dual-channel RF Receiving Front-End with High Linearity for WCDMA/TD-SCDMA

摘要

This paper presents a novel dual-channel RF receiving front-end design used for 3G system. The reasonable solution to front-end is given. The performance of component is simulated by using commercial EDA software. The whole receiver is integrated on a four-layer PCB with small size, low power consumption, high accuracy, high linearity and high sensitivity. Finally, the front-end had been tested and the measured results show that it meets the 3GPP standard perfectly. The solution is also available for dual-channel RF receiver design in cdma2000 and TD-SCDMA.
