Qorvo's New GaAs Process Aims High

News
90nm pHEMT technology targets high frequency amplifiers for 100G+ applications

Qorvo has announced a new GaAs pHEMT technology that it claims provides higher gain/bandwidth and lower power consumption than competing semiconductor processes.

Qorvo's TQPHT09 is a 90nm pHEMT process that supports Qorvo's next-generation optical product portfolio. This new process is said to be ideal for next-generation high frequency, high performance amplifiers required for 100G+ linear applications.

Manufactured in Qorvo's GaAs fabrication facility in Richardson, Texas, TQPHT09 is the newest offering in the company's well-established pHEMT process portfolio. Qorvo's TQPHT09 serves as the basis for several new optical modulator driver products including the TGA4960-SL, the company's most advanced quad-channel 100G modulator driver. 

The TGA4960-SL is available in the CFP2 form factor for Metro and long haul applications, and is also well suited for upgrading the 100G linear dual-channel drivers for line card applications. It is optimised for high performance, low power dissipation and high channel-to-channel isolation, and is packaged in a 14.0 x 8.0 x 2.6mm SMT module, the smallest footprint in the industry.

James Klein, president of Qorvo's Infrastructure and Defense Products group, said, "Qorvo continues to invest and develop the most competitive semiconductor process technologies in the industry, enabling best-in-class components for next-generation products. Qorvo's new 90 nm pHEMT process exemplifies our leadership in providing components for high-speed market applications with the quality, reliability and dependable source of supply our customers expect."



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.
