Industry’s First 28 GHz GaN Front End Module for Fixed Wireless 5G Base Stations

Qorvo has expanded its offering for 5G applications with the first 28 GHz Gallium Nitride (GaN) front-end module (FEM) - the QPF4001. This new FEM reduces overall system costs for base station equipment manufacturers as they expand into 5G.

The QPF4001 FEM integrates a high linearity LNA, a low loss transmit/receive switch and a high-gain, high-efficiency multi-stage PA in a single MMIC. The compact 5x4 mm air-cavity laminate surface mount package is optimized for the phased array element spacing at 28 GHz for 5G base station architectures.

According to SNS Telecom & IT, the 28 GHz frequency band is widely preferred for early 5G-based fixed wireless access (FWA) deployments, enabling operators to meet the speed, latency, reliability and capacity requirements of 5G.

Qorvo’s new GaN FEM enables smaller, more powerful and efficient millimeter-wave, phased array systems, which will steer signals to areas of greater bandwidth demand. Using Qorvo’s highly efficient 0.15-micron GaN-on-SiC technology in this application allows the user to more efficiently achieve higher EIRP levels while minimizing array size and power dissipation, resulting in a lower cost system.

Telecom equipment manufacturers are realizing significant improvements in efficiency and operational bandwidth with Qorvo’s GaN-on-SiC products, which deliver high power density, reduced size, excellent gain, high reliability, process maturity, and volume production dating back to 2000. The QPF4001 complements Qorvo’s portfolio of innovative 5G products, including the 39 GHz FEMs for 5G, announced in June 2017.

Engineering samples of the QPF4001 FEM are available now to qualified customers. For more information, click here.
