Surface acoustic wave (SAW) filters are widely used in radio frequency applications due to their relative ease of fabrication and their high performance level. The B39152B9895P810 is a SAW filter developed by Indian semiconductor and electronics manufacturer, Phulwari Technologies. This filter is used in various applications, including for base-station, digital broadcast, and other telecommunications based applications.

The B39152B9895P810 SAW filter has a low insertion loss with minimized variations over the entire frequency range and designed to offer high rejection of out-of-band signals. This filter involves the combined use of surface wave delay lines and reflectors to create a low power, high performance solution for signal filtering. Its other attributes include low cross-talk and low harmonics, making it a viable solution for wireless applications. The filter is capable of handling a wide frequency range, from 885MHz to 3315MHz, and has a temperature coefficient range of -40°C to +105°C.

The B39152B9895P810 is designed to provide an economical solution for high-performance RF filtering and channel selection. It is simple to use by integrating into existing telecommunications networks, and has low-power capabilities and operational temperature range. The filter also provides high rejection of out-of-band signals, to minimize interference and reduce system noise. The filter is specifically manufactured for rapid and robust applications.

The working principle of this SAW filter is as follows. The filter first employs a series of reflective and transmissive gates and electrodes to define and control the path of the acoustic wave traveling along the surface of the crystal. This wave is then kept constant by the electric field created by the electrodes. This wave is then amplified as it passes through the active part of the filter, which then produces a signal containing the desired frequencies or frequencies of interest.

The active part of the filter is a set of tuned delay lines, which separate and amplify incoming radio frequency signals to generate a signal containing the desired frequencies or frequency bands. These tuned delay lines are connected to the electrodes in the filter and can be tuned by adjusting the value of the capacitors inside the delay lines. By changing the value of the capacitors, different frequency bands can be selected from the signal, and the filter can be used to emphasize certain frequencies.

The B39152B9895P810 SAW filter provides an excellent option for high-performance RF filtering and channel selection. Its simple design, low power requirements, and low temperature coefficient make it a viable solution for efficient signal filtering. The filter is especially useful in telecommunications applications for base-station, digital broadcast, and other wireless applications.
