TriQuint Semiconductor WiFi / WiMAX RF bulk acoustic wave (BAW) 4G filters enable mobile devices to act as portable WLAN (WiFi) hotspots and simultaneously connect directly to 4G WiMAX networks for broadband access up to 10 times faster than conventional 3G systems. TriQuint Semiconductors BAW 4G filters give WLAN handsets, laptops, and similar products fully-mobile, high-speed WiMAX access. Mobile devices using TriQuint BAW filter technology can provide WLAN access for up to 5 connected devices. TriQuint Semiconductor BAW 4G filters are designed for high performance at frequencies greater than 1.5 GHz. BAW technology is particularly adept at solving complex filter challenges such as enabling adjacent bands in the RF spectrum to function at the same time without interference. BAW's ability to provide steep rolloff enables one filter to reject near-in interference while maintaining excellent, low loss performance.
