Airfast RF power LDMOS devices break the 50 percent Doherty efficiency barrier
(International Microwave Symposium) – RF power industry leader Freescale Semiconductor is introducing its second generation of Airfast RF power solutions, delivering a new level of performance for advanced wireless infrastructure equipment, including GSM/UMTS, CDMA/W-CDMA, LTE, and TD-LTE applications.
Freescale’s newest Airfast family of RF power solutions builds on the success and proven performance of the previous generation, which was comprised of 28V discrete, single-stage power amplifiers. Leveraging and enhancing first-generation Airfast circuitry, die, matching network and packaging technologies, Freescale has reached another industry milestone with the next generation of Airfast technology, which includes the first production RF power LDMOS parts to achieve 50 percent efficiency in a Doherty configuration. Additionally, second-generation Airfast power amplifiers expand the portfolio’s breadth to include two-stage integrated circuits, incorporating multiple gain stages in a single package; as well as adding new offerings based on gallium nitride (GaN) and 48V LDMOS process technology.
The new devices are complemented by a broad array of customer solutions and support. Application-specific reference designs give customers a head start in designing and developing a wide range of common systems with configuration and development instructions.
“The second generation of Airfast solutions raises the bar for performance, efficiency and speed-to-market for our customers," said Paul Hart, senior vice president and general manager for Freescale’s RF group. “As the industry leader in RF power amplifiers, our new devices push the envelope across cellular standards and extend Freescale’s innovation to new levels in the wireless market.”
The initial second-generation Airfast products include
