WLAN-Bluetooth filters are suitable for smartphones
Enabling the coexistence of cellular, WLAN, Bluetooth and satellite navigation services on the same antenna, TDK has claimed that the B8831 WLAN-Bluetooth filter offers best-in-class performance and size. The device achieves a much better Q factor than existing components and features a significantly lower insertion loss of only 1.1dB and high out-of-band selectivity.
With the continuously growing number of communication services, the RF spectrum is a limited resource that is becoming ever more densely populated. The WLAN and Bluetooth band between 2400 and 2483MHz is separated by just 20MHz from the new bands 7, 40 and 41 that are used for LTE cellular service.
The B8831 is able to prevent the signals in the adjacent WLAN/Bluetooth and highband cellular bands from interfering with each other. This helps to reduce power consumption in smartphones without affecting performance.
Supplied in an 1109 package, the B8831 WLAN-Bluetooth filter measures just 1.1x0.9x0.4mm.
