EPCOS has introduced a cutting-edge EPCOS wireless local area network (WLAN)-Bluetooth filter designed to support the coexistence of mobile phones, wireless LANs, Bluetooth, and satellite navigation services on the same antenna. The new B8831 filter, built on advanced second-generation BAW technology (BAW2), offers an improved quality factor and significantly reduced insertion loss—only 1.1dB. This makes it ideal for high-performance applications where signal clarity is crucial.
The B8831 comes in an ultra-compact package measuring just 1.1 mm x 0.9 mm, with an even thinner version available at 0.4 mm in height. Its small size allows for greater design flexibility in modern smartphones, making it easier to integrate without sacrificing performance.
With the increasing demand for wireless services, spectrum resources are becoming more limited. The 2400–2843 MHz band used by WLAN and Bluetooth is now very close to LTE bands 7, 40, and 41, with less than 20 MHz of separation. This proximity can lead to interference issues. However, the B8831’s low insertion loss and strong out-of-band rejection help prevent such conflicts, ensuring smoother operation between different wireless technologies.
By reducing interference, the B8831 also helps lower smartphone power consumption without compromising signal quality or user experience. This makes it a key component for next-generation devices that require both efficiency and reliability.
