Freescale Expands GaN RF Offering For Land Mobile Market

The firm maintains its Airfast RF gallium nitride power solutions deliver exceptional performance and industry-leading ruggedness
Freescale Semiconductor has introduced one GaN and three LDMOS (Lateral Double-diffused MOSFET)power transistors to its flagship family of Airfast RF power solutions.

They are all designed to exceed stringent land mobile market requirements for exceptional ruggedness.

The new Airfast GaN device targets multiband applications, where it eliminates the need for large and complex, or even multiple radios.

“Until now, engineers have faced significant challenges in developing multi-band systems that are large, complex and expensive to design," says Ritu Favre, senior vice president and general manager of Freescale’s RF business. “The latest additions to our Airfast RF power portfolio enable exceptional broadband performance to land mobile designers, all within an ultra-compact footprint."

For radio operators and public safety personnel, the ability to communicate with multiple agencies is critical to taking rapid, organised and efficient action during emergency situations.

The broadband performance of Freescale’s new Airfast AFG30S010 GaN device allows a single power amplifier to support many land mobile bands, eliminating the need to design large, expensive and complex multi-band systems for multi-agency communication. Offering high efficiency and advanced thermal performance, the AFG30S010 device provides the functionality to deliver a reduced amplifier footprint, critical to meeting customer demands for smaller product form factors.

The Airfast GaN device operates from a 28 Vdc supply and operates at 10 W across the entire 136-941 MHz frequency band. It can survives over 20:1 VSWR with simultaneous over voltage and overdrive. With improved system reliability and lower maintenance costs, the GaN module eliminates the need for complex protection circuits, which reduces overall system cost further still. Freescale says it also exhibits high efficiency across a wide frequency range.

Sample quantities of the AFG30S010 device are planned to be available in Q4 2013.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
