Surface Acoustic Wave (SAW) filters are passive filters, which manipulate radio waves based on their acoustic properties. Specifically, SAW technology uses sound waves on the surface of a piezoelectric material to filter out only certain frequencies that are desired. This technology has been developed for many decades and has gained extensive use as a filter for electronic communications applications in recent years.

One type of SAW filter that has seen increasing popularity due to its small size and high performance is the SF2314E. The SF2314E filter is capable of suppressing higher order spurious signals that are common within RF communications systems. The SF2314E utilizes two separate, half-wave SAW resonators which allow for a more compact structure without sacrificing performance level capabilities.

The SF2314E’s application field includes wireless or cellular telephone handsets and PDA’s, vehicle communication systems, medical applications and equipment, and land mobile radio systems. It is particularly useful in wireless applications such as Wi-Fi and 3G, and can serve as an alternative to other larger and more expensive filters.

The working principle of the SF2314E filter is based on the propagation of a surface wave along its piezoelectric material substrate. The surface wave propagates periodical moving electric fields, which cause in turn a propagated acoustic wave. This acoustic wave works as a filter and only the frequencies that matches its design are propagated along the substrate.

The SF2314E utilizes two individual SAW resonators, each acting as a half-wave structure. This allows for a more compact structure without sacrificing the performance level capabilities. By using the dual SAW resonators, the SF2314E can filter out frequencies with a high level of accuracy, providing superior performance compared to other filters in the same size range. Additionally, this filter is designed to reduce distortions, increase suppression of out-of-band frequencies, as well as lower adjacent channel noise.

The SF2314E is also extremely temperature stable. By utilizing the material characteristics of the individual SAW resonators, the SF2314E is able to maintain its optimal performance levels over a wide temperature range. Additionally, its temperature stability ensures that the filter does not drift over time and can be used in a variety of temperature environments.

Overall, the SF2314E surface acoustic wave filter is an extremely effective and reliable device. Providing excellent performance and suppression of out-of-band frequencies, the SF2314E is an ideal choice for use in wireless and cellular communication applications. Its small size and temperature stability makes it a great alternative to other larger and more expensive filter options.
