Using MCPAs as active combiners for optimizing the 3G transition 

Apr 1, 2007, By Christopher Zappala and Jeffrey Strahler

Wireless operators have used multicarrier power amplifiers to increase the coverage and capacity of existing base stations. Most often, the MCPAs have operated in TDMA and CDMA environments, and not in GSM systems, until recently. With active combining emerging as the MCPA's primary application, 3G networks are becoming the target for deployment. In addition to describing what is active combining, this article shows how MCPAs can help transition to 3G networks....
