Single-Chip Multiband WCDMA/HSDPA/HSUPA/EGPRS Transceiver with Diversity Receiver and 3G DigRF Interface Without SAW Filters in Transmitter / 3G Receiver Paths

📋 论文概要

本文提出一款单芯片多频段WCDMA/HSDPA/HSUPA/EGPRS收发器，集成分集接收机和3G DigRF数字接口，无需外部SAW滤波器，降低了成本与面积，解决了多模多频段通信的集成难题。

💡 主要创新点

• 无需SAW滤波器的收发器架构，通过片上滤波和线性度优化实现。
• 集成主接收机和分集接收机，支持多天线接收分集。
• 集成3G DigRF数字接口，简化基带与射频的接口。
