SKY85921-11
6 to 7 GHz BAW band-pass filter for Wi-Fi 6E and Wi-Fi 7 full-band applications.
The SKY85921-11 is a Skyworks bulk acoustic wave band-pass filter that operates across 5945 to 7125 MHz, covering the 6 GHz band used by Wi-Fi 6E and full-band Wi-Fi 7. It passes the 6 to 7 GHz band while rejecting out-of-band signals, which lets a Wi-Fi 6E or 7 radio use the wide 6 GHz spectrum without interfering with adjacent services or being disturbed by them. BAW technology gives the steep skirts that the crowded 6 GHz environment requires, and the compact package lets a designer add that filtering without a large board penalty. The filter is a natural companion to a 6 GHz front-end module or LNA and is used in access points, routers, mesh nodes and client devices that support the newest Wi-Fi bands. As Wi-Fi 7 pushes into the 6 GHz spectrum, filters like this become essential to coexistence, because the band sits next to cellular and other services. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports band planning and layout.
FAE Professional Review
As Wi-Fi moves into the 6 GHz band, the filtering requirement becomes harder, and this BAW filter is built for exactly that. Its steep skirts keep the 6 to 7 GHz band clean next to neighbouring services, which is what lets a Wi-Fi 7 radio use the full band. Pair it with a 6 GHz front-end module and confirm the coexistence margins, because the band is crowded.

Frequently Asked Questions
Which Wi-Fi bands does this filter cover?
It operates across 5945 to 7125 MHz, covering the 6 GHz spectrum used by Wi-Fi 6E and full-band Wi-Fi 7.
Confirm the exact sub-bands your design uses against the filter response.
Why is filtering so important at 6 GHz?
The 6 GHz band sits next to cellular and other services, and Wi-Fi 7 uses a wide portion of it, so steep filtering is needed to coexist without interference.
BAW filters provide the sharp transition that the band requires.
