Surface acoustic wave (SAW) filters are highly efficient, low cost and compact filters used to filter out unwanted frequencies in an electronic device such as a radio receivers. The B39380K6264K100 is a SAW filter and is used in a wide variety of applications. In this article, we will be discussing the application fields and working principle of this SAW filter.

The B39380K6264K100 is a bandpass SAW filter which has low noise and is highly efficient. It offers low insertion loss and good stopband attenuation performance. It has a center frequency of 2.45 GHz and a bandwidth of 200 MHz. This SAW filter is used in a wide range of applications including mobile phone base stations, Bluetooth and Wi-Fi devices, wireless audio systems, video transmitters and receivers, digital modems and satellite receivers.

The B39380K6264K100 SAW filter has several key features which makes it suitable for various applications. It offers a high selectivity of up to 50dB, low insertion loss, good RF shielding, low profile and high level of repeatability. It also has excellent linearity and temperature characteristics which makes it ideal for use in demanding radio applications.

The principle of operation for a SAW filter is based on the fact that a sound wave can travel through a piezoelectric medium. When a signal enters the SAW filter the acoustic wave propagates across the piezoelectric medium and when it reaches the other end, it is converted back into an electrical signal. The frequency of the signal is then compared to a reference frequency which is typically supplied by an oscillator. If the signal frequency matches the reference frequency it is allowed to pass through the filter. However, if the signal frequency does not match, then it is rejected by the filter.

The B39380K6264K100 is an example of a SAW filter which is used in a wide range of applications. It has low noise, high selectivity, low insertion loss, excellent linearity and temperature characteristics which makes it suitable for use in demanding radio applications. Furthermore, its small size and low profile make it ideal for use in space-constrained environments.
