Macom Launches Plastic Packaged Chip For RF Energy Applications

New transistor delivers GaN performance and silicon cost structures at greater power efficiency and density than LDMOS

Analogue RF and microwave company Macom has announced a plastic-packaged 300W GaN-on-silicon rugged power transistor for use in commercial scale solid-state RF energy applications.

Based on Macom's Gen4 GaN technology, the new MAGe-102425-300 is said to deliver performance that defies the inherent power efficiency and density limitations of LDMOS at an equivalent price profile at scaled volume production levels.

The combination of GaN performance and silicon cost structures offers an opportunity to use solid-state RF energy as an efficient and precise heat and power source for many commercial applications including microwave ovens, automotive ignition, lighting systems and industrial, scientific and medical (ISM) applications including RF plasma lighting, material drying, blood and tissue heating and ablation, and beyond.

Providing 300W output power and 70 percent efficiency at 2.45 GHz, the MAGe-102425-300 meets the core technical requirements for next generation power amplifiers proposed by the RF Energy Alliance, a non-profit technical association dedicated to unlocking the potential of RF energy. Meanwhile the cost structure and volume supply chain benefits achieved with Macom's Gen4 GaN technology position the MAGe-102425-300 to meet aggressive cost targets on a par with LDMOS, according to the company.

"Solid-state RF energy technology holds the promise to transform entire market segments, providing wide-ranging benefits from consumer goods to ISM systems and infrastructure," said Mark Murphy, senior director of marketing, Macom. "The MAGe-102425-300 sets a new price and performance benchmark for RF power devices, affirms Macom's GaN technology and application expertise, and signals a clear inflection point in the evolution toward mainstream RF energy adoption."

"The RF Energy Alliance recently published the RF Power Amplifier (PA) Roadmap, which sets parameters for future PA module generations that are viable alternatives to magnetron-based solutions," said Klaus Werner, executive director of the RF Energy Alliance. "The MAGe-102425-300's breakthrough in efficiency is in step with our PA Roadmap, enabling new markets for residential solid-state RF energy applications."

Macom will be featuring the MAGe-102425-300 at the International Microwave Symposium 2016 (IMS), May 22nd-27th in San Francisco, California. 

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.
