Surface Acoustic Wave (SAW) filters are a type of high-frequency filter used to manipulate the frequency spectrum of electrical signals. They are commonly used in communication systems, such as Mobile Telephone Networks, Radio Broadcasting, Satellite Links and Defense Applications. The B39172B4307F210 is a SAW Filter specifically designed for use with mobile phones.

The filter\'s core technology is a surface acoustic wave, which is converted into an electrical signal by a receiving device. The wave is generated by a mechanical device which vibrates at ultrasonic speed. The output frequency of the device is determined by the physical layout of the filter\'s components. It works by selecting only certain frequencies from the electrical signal and blocking out others.

The filter is built using a multiplicity of thin resistive layers bonded with two layers of electrodes on both sides. The top and bottom layers are arranged in an alternating pattern to form a crossed-strip filter. This allows the filter to have a narrow band of frequencies, which are selected from the input signal. The resistive layers act as absorbers, reducing the signal level and improving the selectivity of the filter.

The B39172B4307F210 has a center frequency of 819MHz and a bandwidth of 65MHz. It has a passband ripple of 0.15dB and an insertion loss of 1.5dB. The filter is designed to operate over a temperature range of 0ºC to 70ºC and withstand a maximum power of 10 watts. It is also hermetically sealed, so it is able to withstand harsh environmental conditions. The filter is also RoHS compliant, which means it does not contain any hazardous materials that are dangerous to the environment.

The B39172B4307F210 is a highly specified SAW filter, making it ideal for applications in the mobile phone industry. It is able to handle a wide range of frequencies, making it suitable for use with different networks and technologies. The high level of accuracy and precision of the filter is also beneficial, as it ensures it is able to deliver the desired frequencies with minimal losses. This ensures that signals are not affected by interference or background noise, thereby providing a higher quality signal.

The SAW filter is also highly reliable, as it is able to withstand environmental conditions, including extreme temperatures, moisture, dust and radiation. Additionally, the filter is available in a range of sizes, making it suitable for different applications. This makes it an invaluable tool for the mobile phone industry, as it allows mobile phone networks to be tailored to different geographic regions and network technologies.

The B39172B4307F210 is a highly advanced SAW filter, making it ideal for use in the telecom industry. Its ability to select specific frequencies from a signal and attenuate unwanted frequencies is a valuable asset for a range of applications. With its high level of accuracy and wide temperature range, the filter is an indispensable component in telecommunications networks.
