PALADIN Supports 3G CDMA2000 1xEV-DO
17th February , 2004

US : PMC-Sierra announced enhancements to the PALADIN(R) family of digitally-based processors used in wireless base transceiver stations (BTS), the equipment required to link wireless handsets to voice and data networks. The enhanced PALADIN architecture incorporates new features to simplify the design of 3G wireless base stations for WCDMA and CDMA2000. Notably, the updated PALADIN architecture now supports 1xEV-DO, the newest generation of CDMA2000 technology. In Asia, CDMA2000 1xEV-DO is already being used for videoconferencing on wireless handsets. PMC-Sierra's new PALADIN architecture enables OEMs and module vendors to build the next-generation BTS today.

"Our 2G, 2.5G, and 3G CDMA customers in Asia, Europe, and North America can seamlessly upgrade their existing BTS systems with our latest PALADIN architecture and significantly reduce developmental time and costs," said Bill Richardson, manager of Strategic Marketing, for PMC-Sierra's Service Provider Division. "Since our PALADIN processors are designed to accept digital baseband signals directly, as required by new industry interoperability specifications, system vendors deploying the PALADIN architecture will have a head start in implementing emerging standards such as OBSAI and CPRI."

PMC-Sierra's third generation PALADIN architecture utilizes digital pre-distortion (DPD) technology to improve power efficiencies by more than 50 percent over traditional analog feed-forward solutions, providing substantial OpEx savings for wireless carriers. In addition, DPD technology eliminates many complex analog components from the base station systems. By replacing these expensive analog components with simple and compact digital circuitry, OEMs can reduce CapEx today and take advantage of Moore's Law to realize additional savings in the future.

Integrating Enhanced PALADIN Features

The enhanced PALADIN architecture uses the new PALADIN 10/15 Release 03 Firmware. The firmware includes extended support for CDMA2000 1xEV-DO and Automatic Gain Control (AGC) to improve linearization performance and reduce cost and time in the factory. A user-configurable training signal also has been incorporated into the firmware that eliminates the need for factory test equipment and extra circuitry to initialize the PALADIN device's compensation parameters. Using the internally generated signal has the added advantage of reducing factory training time.

PMC-Sierra's PALADIN Product Family

The PALADIN family includes the new PALADIN 10/15 Release 03 Firmware, PM7800 PALADIN 10, PM7815 PALADIN 15, and PM7819 PALADIN Waveshaper(TM) devices (see Figure 1). All PALADIN devices support both WCDMA and CDMA2000 technology and work seamlessly together. The PALADIN 10 is suitable for up to 2-carrier WCDMA and up to 8-carrier IS-95/CDMA2000 systems. The PALADIN 15 is suitable for up to 3-carrier WCDMA and up to 12-carrier IS-95/CDMA2000 systems. The PALADIN Waveshaper performs digital multi-carrier combining and crest-factor reduction optimized for WCDMA and CDMA2000 systems.
