Qorvo adds GaN power amplifier

What is a GaN power amplifier? What does it do? June 20, 2019 - Qorvo®, Inc. (Nasdaq: Qorvo), a leading provider of core technologies and RF solutions for mobile, infrastructure and defense applications QRVO) today announced the release of two new gallium nitride (GaN) power amplifier (PA) series products---QPA2212 and QPA1022, which are suitable for international Ka-band satellite communication applications and X-band phased array radar applications. These solutions deliver the industry's highest levels of power, linearity and efficiency in a smaller form factor, so both devices improve system performance while reducing costs.

QPA2212 is suitable for Ka-band applications, enabling the linearity of broadband multi-carrier systems to reach the highest level in the industry. This power amplifier delivers 20 watts of RF power in the 27-31Ghz frequency band. Additionally, there are 14-watt QPA2211D and 7-watt QPA2210D options. The higher the linear power provided by a single MMIC PA, the greater the potential for cost reduction and performance improvement. QPA2212D is now available in bare chip version, and the packaged version will be launched in August 2019.

The QPA1022 is suitable for X-band phased array applications and provides excellent power-added efficiency in the 8.5-11 Ghz range - up to 45% at 4 watts of RF power. Compared with previous products, the efficiency is increased by 8%, and it can also provide 24 dB large signal gain. These features significantly increase power and reduce heat, enhancing reliability and lowering cost of ownership. For the same power budget, designers can now create higher-density arrays, extending the power available over a wider range. QPA1022 is now available to customers in package and bare chip versions.

Dean White, director of market strategy for defense and aerospace at Qorvo, said: "These new amplifiers will expand Qorvo's existing large product portfolio to provide differentiated GaN products for defense applications. The advanced features and advanced packaging technology of the two new products make full use of our 30 Years of professional experience in designing and providing RF solutions in this market also provide feasible solutions for the commercialization of 28GHz 5G network design."

Qorvo provides the industry's most comprehensive and innovative GaN-on-SiC product portfolio, helping customers significantly improve efficiency and operating bandwidth. Qorvo products feature high power density, small size, excellent gain, high reliability and mature processes. Mass production began in 2000. The above is Qorvo’s new GaN power amplifier suitable for Ka-band and X-band applications. I hope it can be helpful to everyone.
