B39841B8768P810S5 Filters

SAW filters are a type of micro-electronic device used for the rapid transmission of signals over a variety of frequencies. SAW filters have various applications that range from consumer electronics such as cellular phones to industrial uses such as medical diagnostics and vibration testing. The B39841B8768P810S5 is a particular type of SAW filter designed to regulate the frequency output of an RF signal.

The B39841B8768P810S5 SAW filter is a multi-pole low-pass filter designed to combine very low insertion loss with a sharp cutoff slope. The configuration of this SAW filter contains eight differential transmission lines, which is also known as a pi-network, and is constructed with a thick-film technology on a glass substrate. The B39841B8768P810S5 delivers very low insertion loss of up to 0.5 dB, an exceptional rejection (elimination) of out-of-band signals, and excellent phase ripple characteristics.

The primary application areas of the B39841B8768P810S5 SAW filter are as a pre-selector filter, or an amplitude equalizer for radio communication systems and mobile phones. The SAW filter typically comes as a low-pass filter in the intermediate frequency band. This filter gives the equipment a sharp guard band, and allows it to be quickly tuned from one filter passband to another without interfering with other communication signals.

The B39841B8768P810S5 SAW filter works on the principle of acoustic-wave propagation within a resonance cavity. Acoustic waves are generated and propagated along a piezoelectric substrate, which is between two interdigital fingers. The filter works as an energy transfer element, allowing signals within a certain pass-band to pass through while blocking signals outside the pass-band. The frequencies that are blocked out are then reflected out of the filter, allowing only the signals within the pass-band to come out of the filter.

The B39841B8768P810S5 SAW filter has an excellent stop band rejection, and a very low insertion loss, making it suitable for applications that require precise signal conditioning. This SAW filter can also be used with wideband signals, thereby allowing it to be used for multiple signal types. The frequency range of this filter is 800MHz~3000MHz, making it a versatile filter for many applications, from industrial to medical.

In summary, the B39841B8768P810S5 SAW filter is a highly efficient and effective device that is useful for a variety of applications. It works on the principle of acoustic-wave propagation, allowing only the frequencies within its pass-band to enter, and blocking out all signals outside the predefined range. This type of SAW filter is typically used as a pre-selector, or an amplitude equalizer for radio communication systems and mobile phones. The frequency range of this filter is 800MHz~3000MHz, making it ideal for a variety of applications.
