Extending its leadership and innovation in RF technology for wireless infrastructure, Freescale Semiconductor Inc., a wholly owned subsidiary of Motorola Inc., has added sixth-generation RF products to its line of LDMOS (laterally diffused metal oxide semiconductor) power transistors for 2.5G and 3G wireless infrastructure applications.

Freescale's extensive portfolio of RF LDMOS transistors enables wireless infrastructure designers to develop cost-effective, highly efficient cellular base station amplifiers supporting GSM, EDGE, CDMA and W-CDMA technologies. As a leader in LDMOS technology, Freescale designs its RF power transistors to provide outstanding power density, exceptional RF performance, high quality and reliability, superior device consistency and high efficiency, as required by wireless infrastructure applications.

Freescale continues to drive state-of-the art RF technology by delivering a full line of ceramic and plastic-packaged products based on the company's sixth-generation RF LDMOS technology. As a pioneer in RF technology, Freescale has achieved a number of milestones, including:

? First to develop RF power transistors in LDMOS technology,

? First to implement industry standards in ceramic and plastic packaging,

? First to install electrostatic discharge (ESD) protection on RF devices,

? First to offer RF products that support hundreds of years of "mean time to failure" (MTTF), and

? First to deliver a 2 GHz discrete RF power transistor in cost-effective plastic packaging capable of a 200C maximum operating junction temperature.

Manufacturers of wireless infrastructure equipment continue to have flexibility in choosing high-voltage ceramic or plastic RF transistors from the same reliable, high-volume semiconductor supplier. Initial members of Freescale's sixth-generation LDMOS ceramic family include the MRF6S19100H/S, MRF6S19140H/S, MRF6S21100H/S, and MRF6S21140H/S devices. Freescale's sixth-generation LDMOS plastic family provides a reliable, robust and economical alternative to ceramic. The plastic family initially includes the MRF6S19060N/NB, MRF6S19100N/NB, MRF6S21060N/NB, and MRF6S21100N/NB devices.

Freescale offers RF designers a comprehensive library of modeling and simulation tools that can help fully characterize the RF product offerings in a computer aided design (CAD) environment. This modeling and simulation capability can result in reduced design time and faster time to market.
