Aperture tuning is essential in enabling smartphones to operate efficiently over increasing RF frequency bands and support transitions to 5G. Proper tuning enables antennas to operate efficiently on multiple bands and increases Tx and Rx performance. Implementing aperture tuning requires in-depth knowledge of how to apply the technology for smartphone application.
Smartphone manufacturers are introducing full-screen handsets with an 18:9 screen aspect ratio. The form factor hurts antenna performance, resulting in poorer connectivity and lower data rates unless compensated for by the RF front-end. This Qorvo white paper discusses these challenges faced by phone designers and offers solutions.
Accelerating 5G standards development is creating pressure for smartphone manufacturers to add 5G new radio (NR) support to handset designs. 5G introduces new challenging requirements and initial mobile deployments will create additional complex RF challenges. Innovative new RF solutions will be required to solve the complex challenges of 5G.
Qorvo reported revenue and earnings above guidance for fiscal Q2 of 2018, reflecting volume from mobile phone ramps at Apple and Chinese manufacturers and strong demand from the defense, Wi-Fi and IoT markets. During the quarter, the company took “targeted actions” that reduced headcount by some 300 people.
