L-band power transistor portfolio targets avionics markets
Freescale Semiconductor is expanding its L-band portfolio with two Airfast RF power transistors featuring exceptional system function integration and broadband high power performance. The latest AFIC10275N and AFV121KH products provide benefits that help meet the exacting standards of the world’s leading air traffic control (ATC) systems manufacturers.
Worldwide ATC and aircraft-to-aircraft communications requirements are growing more stringent, and airplanes will need to carry increasingly sophisticated tracking and communications systems in the years ahead.
Size, weight and power are critical parameters for avionics applications. The AFIC10275N claims to be the industry’s first RF power integrated circuit covering the 978 to 1090 MHz band, and helps customers address these market criteria by enabling much smaller and lighter power amplifier (PA) transponders. The AFIC10275N integrates two amplification stages in a plastic package, delivering 250 W with 31 dB of gain and 64 percent drain efficiency. It also embeds temperature and RF sensing capabilities, reducing the need for external components. The device is available with a reference circuit that reduces cycle time and development costs for customers.
The AFV121KH transistor delivers 1 kW of power with 59 percent efficiency and more than 1.2 kW of power with 51 percent efficiency across the 960 to 1215 MHz band, and is capable of even higher power when tuned for narrowband performance at 1030 MHz. Higher power allows customers to reduce part counts, thereby enabling significant cost savings.
The AFIC10275N is currently in production. The AFV121KH is sampling now and scheduled for production in Q3 2015. Freescale offers global applications support, compact reference designs, as well as ADS and AWR tools to support the latest Airfast RF power products for avionics.
