Surface acoustic wave (SAW) filters are having a great impact in the world of electronics. They are used to eliminate unwanted signals within the frequency ranges that are being utilized by an electronic circuit. AFS14A35-1902.00-T3 is a type of SAW filter specifically designed for wireless communication applications.

SAW filters are able to filter out undesired signals through the generation of an acoustic wave along the surface of a substrate material. The substrate material, such as quartz or lithium niobate, is designed to interact with incoming electrical signals and is capable of making magnified and reduced versions of those signals depending on the signal’s original frequency. This filtering process is based on the configurations of the multiple electrodes and interdigital transducers (IDT) which are on the surface of the substrate.

The electrodes and IDTs of a SAW filter use transduction to convert the electrical signal into an acoustic wave, and vice versa. When an electrical signal passes through these components, it is simultaneously converted into an acoustic wave or surface wave that is capable of being propagated along the substrate surface and picked up by a receiving unit. The rate of transmission, or frequency, of the acoustic wave is dependent on the properties of the substrate material and the design of the electrodes and IDT.

The AFS14A35-1902.00-T3 SAW filter makes use of a specifically designed combination of electrodes and IDTs that allow for improved performance when applied to a variety of wireless communications settings. In particular, it has been designed for use in applications such as Wi-Fi and LTE devices. It consists of two identical transducers, referred to as ‘fingers’, that are connected in series. These transducers are spaced at a certain distance apart in order to reduce the amount of interference within the frequency range of operation for the filter.

When the AFS14A35-1902.00-T3 is used in a wireless communication setting, it will filter out the undesired signals within the relevant frequency range. This is done through the process of transduction, where each finger of the transducer is alternated between being in a ‘high’ and a ‘low’ state. Due to the spacing between the two fingers, this will cause a slight displacement in the acoustic wave that passes through them, and the filter will then be able to pick up this displacement and effectively filter out any undesired signals.

The AFS14A35-1902.00-T3 SAW filter is a highly effective element for wireless communication settings. It is designed to help reduce interference within the operating frequency range and to improve the overall performance of the device. By seeing the way in which the SAW filter is able to use the transduction process to convert electrical signals and filter out unwanted signals, it is easy to see why these devices are so important in modern electronics applications.
