B39182B4133U510

SAW (surface acoustic wave) filters are a type of filter that uses acoustic waves on the surface of a piezoelectric substrate to process electrical signals. The B39182B4133U510 is an example of such a filter, which is used in radio communication across various markets, such as cellular, automotive, consumer, medical, industrial, and military/aerospace.

The B39182B4133U510 SAW filter is designed to provide high-precision filtering in signal reception for GSM and UMTS/UMTS-TDD standards, which are used for 3G cell-phone communication. It is a surface mounted device (SMD) and is used in radio modules, base stations, cell-phone repeaters, and so on. It is also suited for similar applications with other standards, such as PHS and AMPS.

The frequency range of the B39182B4133U510 is 800 to 960 MHz. Its bandwidth is 6 MHz. It has an insertion loss of less than or equal to 5 dB, and noise and harmonic suppression of at least 50 dB. The source and load impedance is 50 Ω, making it also suitable for use as an impedance transformer. The environmental range of the filter is from -25 C to +85 C.

The working principle of the SAW filter is based on piezoelectric material that generates standing wave patterns on its surface when electric fields are applied to it. These wave patterns are then used to filter out two types of information, either frequency passband or the stopband. The filter also uses metal plates to reflect and transmit sound waves which helps the filter to handle relatively high frequency signals.

The specific working principle of the B39182B4133U510 SAW filter is based on interdigital transducers, which induce standing waves between two plates that are exposed to electric fields. These fields cause the sound waves to interact with an area of the substrate containing finger-like transducers. The filter can then be tuned to specific operating frequencies by adjusting the dimensions of the finger-like transducers, which in turn produces acoustic wave resonators in the SAW filter.

To summarize, the B39182B4133U510 SAW filter is used in radio communication across various markets, including cellular, automotive, consumer, medical, industrial, and military/aerospace. It is typically used in radio modules, base stations, cell-phone repeaters, etc. It has a frequency range of 800 to 960 MHz and an insertion loss of less than or equal to 5 dB. The operating principle is based on interdigital transducers and sound waves interacting with an area of the substrate containing finger-like transducers.
