B39202B7740C810 Filters

SAW Filters are one of the most reliable components used in radio frequency (RF) circuits. Popularly known as surface acoustic wave (SAW) filters, they are used to filter out unwanted signal frequencies. The B39202B7740C810 SAW Filter is a high performance SAW filter designed for ease of use in RF applications, providing excellent attenuation and low insertion loss.

The filtering mechanism of SAW filters are based on the propagation of surface acoustic waves along a piezoelectric material surface. These acoustic waves are generated by interdigital transducers (IDT), which are arrays of metallic electrodes buried in the substrate surface. Two IDT are used in the SAW filter - one for generating the wave, the other for detecting it. The frequency response of the filter is defined by the geometry of the IDT and the characteristics of the substrate material.

The B39202B7740C810 SAW Filter is a wideband RF filter that operates in the 800 MHz band with 805 – 825 MHz pass frequency. It is a single-ended IDT design that includes two IDTs with a shunt capacitive coupling between them. The filter provides 50 dB rejection and less than 0.25 dB insertion loss, making it ideal for applications that require superior performance. It also features an Rf power rating of up to 45 dBm with a low current draw. The filter also has a fast response time of 10 microseconds and is designed for easy installation and configuration.

The B39202B7740C810 SAW Filter has a wide range of applications in the RF industry, including communications equipment, cellular networks, wireless LAN networks, and more. It is suitable for use in both residential and commercial settings, as well as in industrial applications. By filtering out unwanted frequencies, it ensures that RF signals are clean and of the highest quality. This allows for more reliable connections and better performance.

In summary, the B39202B7740C810 SAW Filter is a high performance filter designed for ease of use in RF applications. It provides excellent attenuation and low insertion loss with fast response time and a wide range of applications. By filtering out unwanted signal frequencies, it ensures that RF signals are of the highest quality.
