RF – radio frequency technologies
RF – Radio Frequency technologies
The transition to the 5G implementation has a strong influence on the landscape of the radio frequency technology (RF). At the same time, the importance of radio frequency technologies is more and more increasing as a result of the demands made by autonomous driving and the Internet of Things (IoT). In the field of mobile communication, 5G smartphones require an improved efficiency and a large bandwidth which results in an increased number of filters (up to three times the former number) with much smaller geometries.
These challenges require much more precise and in many cases 100% inspections as well as 3D measurements. The Confovis WAFERinspect AOI offers specific solutions for the inspection of demanding resonator structures and RF components for the serial production.
