SAW (surface acoustic wave) filters are used for a variety of applications, including radio and television transmitters, cellular communications, radar systems, and avionics. B39202B9807P810A99 SAW filter is a type of filter that uses surface acoustic waves (SAWs) to filter out unwanted signals. It is a high-frequency device with a center frequency of 2.8GHz, a passband range of 500kHz, and a stopband attenuation of up to 70dB.

A SAW filter consists of two main components: an interdigital transducer (IDT) and a surface acoustic wave (SAW) device. The IDT consists of two sets of metal electrodes arranged in a crossed-finger pattern on a piezoelectric substrate. When a voltage is applied to the IDT, the piezoelectric effect causes the material to vibrate, creating a series of standing waves on the surface of the device. The SAW device is an acoustic waveguide which is designed to guide the acoustic waves from the IDT to the output of the filter.

B39202B9807P810A99 SAW filter works by using the SAW to selectively pass or reject certain frequencies. The filter is designed to pass a center frequency of 2.8GHz and reject all other frequencies within a 500kHz bandwidth. When an electrical signal is applied to the IDT, the acoustic wave is generated and propagates along the SAW device. The resonator structure of the device is designed to amplify or attenuate certain frequencies, allowing the signal to pass or reject depending on its frequency. By controlling the way the IDT is configured and the resonator design, the filter can be tailored to pass or reject specific frequencies.

B39202B9807P810A99 SAW filter offers a wide range of applications in various fields such as cellular base station filters, avionics, satellite communications, radar systems, and mobile radio. In cellular base station filters, SAW filters are used to select the desired channel and reject all other channels. In avionics, SAW filters are used to separate transmit from receive signals to avoid interference. In satellite communications, they are used to separate signals from multiple satellites. In radar systems, they are used to filter out noise and other unwanted signals. Lastly, in mobile radio, they are used to reject adjacent channel interference.

In conclusion, B39202B9807P810A99 SAW filter is a versatile device that is widely used in many applications such as cellular base station filters, avionics, satellite communications, radar systems, and mobile radio. The device uses an IDT and a SAW device to selectively pass or reject certain frequencies while providing excellent stopband attenuation. With its wide range of applications and its ability to be tailored to specific frequency requirements, SAW filters are a great choice for any application where high-frequency filtration is required.
