Single-Chip RF CMOS UMTS/EGSM Transceiver with Integrated Receive Diversity and GPS

📋 论文概要

该论文介绍了一款单芯片RF CMOS收发器，支持UMTS/EGSM多频段、集成接收分集和GPS功能，解决了多模多频段蜂窝通信中单芯片集成、SAW滤波器减少和低功耗的需求。

💡 主要创新点

• 在单芯片上集成了UMTS/EGSM收发器、接收分集和GPS，减少了外部元件（如SAW滤波器）。
• 实现了多频段多模式操作，支持四频EGSM和多频WCDMA/HSPA接收分集。
• 通过集成的接收分集和GPS提高了接收性能和定位能力，同时降低功耗和成本。

State-of-the-art solutions require quad-band EGSM combined with multiband WCDMA/HSPA receiver diversity and integrated GPS. Compact form factors make single-chip SAW-less solutions highly desirable. A Quad-Band GSM/EDGE-only transceiver was published in [1], and TripleBand WCDMA-only transceiver solutions were published in [2-4]. This work describes the first multiband WCDMA/HSPA/EGPRS single-chip transceiver with GPS and receiver diversity. This device supports UMTS Bands
