How To Improve Wi-Fi Performance Using BAW Filter Technology

As wireless communication demand surges, Wi-Fi Customer Premises Equipment (CPE) access points must manage increasing interference challenges. Tri-band Wi-Fi 6 and 7 improve bandwidth and capacity, yet also introduce self-generated interference, which can degrade network performance. This interference, caused by multi-band transmitters operating within the same device, leads to RF receiver desensitization, reducing signal clarity and connection reliability.

RF filters are essential in mitigating these issues, ensuring proper isolation between transmit and receive paths. Without effective filtering, overlapping Wi-Fi bands can experience significant spectral regrowth, impacting adjacent frequencies and causing performance degradation. In high-density RF environments, filters must possess low insertion loss, steep filter skirts, high rejection levels, and compact size to function efficiently.

Qorvo's Bulk Acoustic Wave (BAW) filters excel in addressing these requirements. With industry-leading Q-factors, they minimize insertion loss, maintain high rejection levels, and ensure seamless Wi-Fi operation. These filters play a crucial role in compliance with regulatory standards and coexistence between Wi-Fi bands and external systems. Their implementation in CPE APs prevents performance degradation when utilizing wider bandwidths, such as 320 MHz channels in the 6 GHz spectrum.

As Wi-Fi demand grows and RF spectrum congestion intensifies, high-quality filters will be integral to ensuring stable and high-performance connectivity. Qorvo’s innovative solutions provide optimal filtering, ensuring seamless, interference-free wireless communication.
