digital RF processorSWPY005 - February 2004 White PaperBackground on the Digital RF Processor (DRP): Revolutionary Approach to Wireless CommunicationsThe basic paradox of developing cellular handsets is that even as the complexity of these devices increases, users continue to demand products that are lighter weight, less expensive, and more power efficient. Complexity is driven by today's cellular handsets having to support multi-band transceivers, diverse modulation schemes and multiple protocols. Add to the mix color displays, cameras, GPS location technology, Bluetooth personal area networking, and wireless LAN (WLAN) connectivity for high-speed local-area data access, as well as enough processing capacity and additional memory to support digital audio and video, games, and PDA applications, and you've ……
