Surface acoustic wave (SAW) filters are used in many applications, such as radio receivers, wireless communications systems, and television receivers. SAW filters offer many advantages over other types of filters such as low loss, wide frequency range, linear response, and low power consumption. The B39881B9851P810A99 is a SAW filter, specifically designed for use in applications with a wide frequency range.

The B39881B9851P810A99 filter is a third order filter, which means it can reject high frequency signal components up to three times the cutoff frequency. This type of filter is commonly used in radio and TV receiver applications, where it is used to reject out-of-band signals and improve the signal-to-noise ratio. It can also be used in other applications such as cell phone, WIFI, and Bluetooth devices, where it helps to reduce unwanted RF noise.

The B39881B9851P810A99 filter is constructed from interdigital transducers (IDTs) and a reflective surface, which is usually made from a reflective metal layer. The IDTs act as transducers, converting electrical energy into an acoustic wave, which reflects off the reflective surface and is converted back into electrical energy by the IDTs. By configuring the position, spacing and number of IDTs, the filter can be designed to pass only specific frequencies of interest.

The B39881B9851P810A99 SAW filter is a low power device, able to operate from a single 3V supply and can handle a maximum input power of up to 10 dBm. It is capable of providing excellent out-of-band rejection up to 20 dB and has a bandwidth of 350 KHz. The operating temperature range is from -40°C to +85°C and the filter is designed to meet RoHS requirements.

In conclusion, the B39881B9851P810A99 is a third order SAW filter designed for use in applications with a wide range of frequencies. It is constructed from interdigital transducers and a reflective surface, and is capable of rejecting out-of-band signals and improving the signal-to-noise ratio. It is a low power device, with a maximum input power of up to 10 dBm and a bandwidth of 350 KHz. The operating temperature range is from -40°C to +85°C and it is designed to meet RoHS requirements.
