TriQuint Rases The Bar In GaN Reliability

The firm says its new process enables more robust, high-efficiency gallium nitride (GaN) RF devices
TriQuint believes it has achieved record-setting circuit reliability that exceeds previous industry standards.

The company’s new GaN benchmark supports highly-reliable integrated RF solutions. TriQuint says its new devices use less power, are compact, and serve wide frequency ranges.

Any RF system can benefit from reduced maintenance and longer operational lifetimes arising from increased reliability. These include commercial and defence RF infrastructure, broadband communications, first-responder radios and space-based applications.

“We’re pleased to announce this new GaN reliability milestone," says James L. Klein, Vice President and GM for Infrastructure and Defence Products. “The achievement supports our foundry services and helps us accelerate product development. We are delivering more products and services than ever before."

TriQuint’s TQGaN25 process, qualified to operate up to 40 Volts, has achieved a mean time to failure of greater than 10 million hours at 2000C and greater than 1 million hours at 2250C.

This reliability milestone was achieved with TriQuint’s newly-released Generation II 0.25µm GaN on SiC process utilised for GaN product solutions and Foundry Services.

TriQuint achieved its new GaN performance through in-house development programs. This new reliability also supports objectives of TriQuint’s Defence Production Act (DPA) Title III contract that is funded by the Department of Defence Tri-Services laboratories including the U.S. Air Force, Army and Navy. TriQuint is also reducing manufacturing cycle times and increasing yields while making other GaN enhancements that work hand-in-hand with DPA Title III goals.

All manufacturing enhancements are designed to support greater affordability of next-generation AESA (active electronically scanned array) radars, new EW systems and commercial applications. Defence systems currently in technology development phases have production planned for 2016-2020.

TriQuint announced the reliability of its TQGaN25 process in connection with the Defence Manufacturing Conference (DMC), November 26th to 29th in Orlando, Florida. The company will be in booth #328 or can be contacted to schedule a meeting via the company's website about GaN, GaAs, or advanced acoustic filter technology including SAW and BAW solutions for commercial and defence systems.



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.
