Qorvo Announces 28GHz Range For 5G Networks


High-performance products include GaN-on-SiC to deliver robust amplification in miniaturised footprint

Qorvo has announced broad commercial availability of four 28GHz RF products for 5G base stations. The devices use the company's GaN-on-SiC and GaAs process technologies to deliver high performance in miniaturised product footprints.

Roger Hall, general manager of Qorvo's High Performance Solutions business unit, said: "Qorvo has collaborated with leading telecom OEMs to support more than 20 5G field trials worldwide. With the broad availability of our 28GHz portfolio, telecom providers can leverage the performance, low noise, high efficiency and small footprint of Qorvo's field-proven line-up to quickly and cost-effectively deploy 5G millimeter wave networks."Â 

Qorvo's 28GHz offerings include the QPC1000 phase shifter, which integrates phase resolution with the ability to switch between transmit/receive functions; two transmit products "“ theTGA4030-SM GaAs medium-power amplifier/multiplier and the TGA2594 GaN-on-SiC power amplifier; and the QPA2628 GaAs low-noise amplifier. 

The complete suite of 28GHz transmit and receive solutions is said to improve power efficiency and optimise size to help telecom equipment providers build out 5G trial systems and accelerate the deployment of full millimeter wave 5G base station networks.

According to Joe Madden, founder of industry research firm Mobile Experts, the deployment of 5G will enable mobile operators to deliver mobile data more cost effectively. Madden estimates it costs operators more than $1,000 to deliver a megabit per second of LTE network capacity, and 5G is expected to reduce operator costs significantly. "Our cost model tells us that 5G should be able to achieve a 10x reduction in cost per bit, compared with LTE," Madden said in a 2017 blog post.

Qorvo wireless infrastructure products will be exhibited at the 2017 International Microwave Symposium in Honolulu, Hawaii, June 4-9

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.
