Gapwaves uses Qorvo GaN in 5G active antenna


Company announces active 28GHz 5G-antenna with integrated GaN power amplifiers

Following the release of an active 5G-antenna in August 2018, Gapwaves has announced second release using Qorvo’s GaN-on-SiC technology. The second release of the active 28GHz antenna demonstrates high EIRP with low power consumption while maintaining good thermal handling.

Gapwaves waveguide solutions provide telecom equipment suppliers with a platform to develop mmwave products with exceptional coverage and performance for e.g. 5G Mobile Access or Fixed Wireless Access.

The 28GHz high EIRP beam forming antenna with a high performing filter and transition from PCB to waveguide is a further development from the previous beamforming antenna. The integration of the dual channel GaN front-end module together with the beamforming chip-set demonstrates a state-of-the-art prototype built on standard components and Gapwaves waveguide technology.

Measurements performed on the prototype have shown very good performance, high antenna efficiency with low losses and high EIRP, confirming the results that were presented earlier. The building practice of the active antenna has also shown excellent thermal performance.

The antenna prototype and measurement results will be presented at Mobile World Congress in Barcelona from February 25-28.

“The release of the 28GHz 5G-antenna further emphasises the high performance of Gapwaves waveguide technology. The solution with Qorvo GaN integrated front-ends is very interesting for 28GHz systems such as 5G Mobile Access and Fixed Wireless Access as the test results confirms the combination of high EIRP with low power consumption” says Thomas Emanuelsson, CTO Gapwaves.

“Built on standard components and Gapwaves waveguide technology, this product is one of few on the market that truly demonstrates a solution that meets the requirements of future 28GHz 5G-networks. Power consumption and large coverage are key elements when realizing the future’s millimeter wave mobile networks. Our second release of Gapwaves 5G antenna is really a milestone on this journey” says Lars-Inge Sjöqvist, CEO Gapwaves.

Roger Hall, general manager, Qorvo High Performance Solutions, said: “Qorvo is excited to be supplying products that demonstrate 5G mmW solutions, including Gapwaves unique antenna application. Qorvo’s innovative 5G products leverage decades of millimeter RF design, and have helped conduct dozens of 5G field trials. Our differentiated GaN solutions are now addressing complex network requirements that are making 5G a reality.”
