SAW Filters

Surface acoustic wave (SAW) filters are a type of electromagnetic filter mostly used in high frequency applications. They contain two devices, a receiver connected to a transmitting device, both of which are activated when the filter is in use. The device receives an electrical signal, which is then transmitted to the sending device where it is converted into an acoustic wave. The wave then travels across the surface of a piezoelectric material, which causes the filtering effect. The wave is then reconverted into an electrical signal, before being sent to the receiver.

B39471B4960U510V9 is a SAW filter used in radio frequency (RF) signal transmission for mobile communications. It reduces unwanted interference from outside sources while allowing the signal from the desired source to be transmitted without interruption. The device offers high frequency stability, low pseudo harmonic distortion, and a wide band pass allowing transmission at either low or high frequencies. It has an insertion loss of 4 dB at 4GHz and 4.5 dB at 2GHz, and operates from a supply voltage of 3V.

The B39471B4960U510V9 is a compact SAW filter designed for easily fitting into different consumer electronic devices. It also offers filter bandwidths of 0.1MHz, 0.5MHz, 1MHz and 2MHz for signal receipt and transmission, enabling it to be used in a range of products.

To help reduce electrostatic interference, the device has a range of ‘anti-static’ elements. This includes shielding for the receiving and transmitting circuits, enclosed ceramic and ferrite materials for suppressing any signalling outside the specified frequency band, and an attribute to ground the unit at a low noise level.

The working principle of the B39471B4960U510V9 is based on a mechanical filter. A mechanical filter, such as the SAW filter, works by passing incoming signals through a medium which is vibrationally sensitive, and then using an electromechanical transducer to detect a particular frequency or range of frequencies. It eliminates all incoming signals outside of the specified frequency range, allowing only the signals within the range to be transmitted.

The B39471B4960U510V9 is commonly used in mobile phones, tablet devices, and other consumer electronics. It is ideal for applications where space is at a premium, and where a low power, low interference device is required.

In summary, the B39471B4960U510V9 is a SAW filter used in mobile communication devices, enabling the transmission of radio frequency signals without interference. It has low insertion loss at both low and high frequencies, good frequency stability, wide bandwidth, and various anti-static elements. The device is based on a mechanical filter and is commonly used in mobile phones and tablet devices.
