TriQuint GaN PA Chosen By RF-Lambda

The firm's gallium nitride devices will be used for defence, industrial, aerospace and commercial applications
TriQuint Semiconductor's, GaN power amplifiers have been selected by RF-Lambda.


RF-Lambda is a global microwave products manufacturer, and has developed a new line of high power based on TriQuint GaN transistors. The firm's latest products are currently being qualified in commercial 4G systems, a defence flight system and other defence and aerospace projects.


Reducing part counts and maintaining performance was central to RF-Lambda’s decision, says R&D Director Michael Liu. “We formerly supplied a key customer with two separate GaAs amplifiers to cover two bands. By using TriQuint GaN, we were able to replace those with a single GaN HEMT and cover the full frequency range."


Liu adds,"This increased design flexibility while decreasing production variation. Our customers also benefit by using software to switch bands rather than physically changing hardware, while still achieving necessary power. Our products support some of the world’s leading defence and commercial communications companies."


RF-Lambda is developing other new power amplifiers based upon TriQuint GaN transistors including a 1-18 GHz, 50 Watt device and 20W/40W solutions for 0.1-6 GHz as well as the RFLUPA0706GE (0.7-6 GHz) 7W amplifier.


James L. Klein, TriQuint Vice President and General Manager for Infrastructure and Defence Products comments, “TriQuint is glad to play a role in this new line of high-power amplifiers. TriQuint GaN products offer important size, weight and power advantages that the defence industry was fast to appreciate. We now see more commercial applications using GaN thanks to its advantages, and we look forward to supporting RF-Lambda’s new programs."


Market analyst Strategy Analytics foresees significant GaN growth. “While defence supported GaN in many applications, communication infrastructure utilisation is growing fast. Sat-Com, power and other infrastructure markets are ramping to higher revenues. Strategy Analytics forecasts that the market for GaN microelectronic devices will grow with a compound average annual growth rate of over 34% to approximately $186 million by 2015," says Eric Higham, Director of Semiconductor Practice.


Technical Details


TriQuint’s new GaN high electron mobility transistor (HEMT) devices offer optimized power and efficiency at high drain voltage operating conditions.





RF-Lambda chose the T2G6001528-Q3, which offers typical power added efficiency greater than 50 percent at 15dB gain; its performance can reduce the number of transistors in a design, which also benefits heat management. These advantages can lower part counts, reduce board space and lower overall system costs.


The T2G6001528-Q3 is offered in a low thermal resistance, flangeless package. Samples and evaluation boards are now available.







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.
