Skyworks RF Filter Distributor | SAW and BAW Filters

BeiLuo supplies genuine Skyworks acoustic-wave RF filters, the SAW and BAW devices that select bands and keep radios from interfering with one another. A filter passes the wanted band and rejects everything else, and as radios crowd the spectrum, the quality of that rejection decides whether a device coexists with its neighbours or degrades them. Surface acoustic wave filters cover the lower bands economically, while bulk acoustic wave filters handle higher frequencies and steeper skirts, which is why they are used for Wi-Fi 6E and Wi-Fi 7 bands and for crowded cellular bands. Skyworks manufactures both technologies and offers compact filters in packages as small as 2 by 2 millimetres, which lets a designer add filtering without a large board penalty. The filters are used in Wi-Fi, cellular, GNSS and infrastructure radios, where they protect receivers from out-of-band blockers and keep transmitters within their spectral mask. Choosing a filter is a trade-off among band, bandwidth, insertion loss and rejection, and our FAE team helps match the part to the coexistence requirements of the design. Because the band and the required rejection decide the technology, our team helps customers choose between SAW and BAW for each band and validate the result on the bench. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file.
