Title: Optimized Silicon Wafers: The Ultimate Solution for Improved RF Filter and Device Performance

Date: April 21, 2021

Time: 8am PT / 11am ET

Sponsored by: Okmetic

Presented by: Dr. Atte Haapalinna, Chief Technical Officer and Petri Santala, Customer Support Manager

5G and the wider bands, lower latency, greater connectivity and higher frequencies are setting new performance standards for RF filters and other RF devices (IPDs, switches, amplifiers, antenna tuners, etc.). There is also added pressure on new product innovations to overcome the mobile industry’s interference challenges and more stringent parameter requirements. Additionally, new kinds of characteristics and performance is expected from the substrates as the entire smartphone value chain struggles to find the perfect balance between improved performance, increased functionality and cost pressures.

The choice of substrate has a significant effect on the performance and TCO of RF filters and other RF devices, which is why the demand for tailored, process-optimized substrates has surged. In this webinar, technical experts from Okmetic discuss the typical challenges RF manufacturers are encountering and the latest silicon wafer solutions developed to tackle these challenges. Okmetic is the world’s leading supplier of advanced silicon wafers for the RF/power and MEMS/sensor market and the seventh largest silicon wafer supplier in the world. Okmetic has an entire line of high resistivity RFSi™ wafers targeted for the RF market that are optimal for all types of acoustic wave filters, IPD devices, power amplifiers, integrated RFIC power amplifiers, as well as silicon interposers. Tune in to learn more about the latest substrate trends in the RF market.
