SAW Filters

A Surface Acoustic Wave (SAW) filter is a filter with an electrical input signal that is converted to an acoustic wave by a transducer. The transducer has a series of metal electrodes which are used to create and receive the waves, so that an electrical signal is converted to an acoustic wave and then back to an electrical signal. Each filter is limited to a frequency between 50MHz and 3GHz. 


Bandpass filters

The most common types of SAW filters are known as bandpass filters. These are generally small and offer a range of advantages, such as the ability to conduct during a relatively low-frequency operation.


What are saw filters used for?

SAW filters are commonly used in many different industries including chemical, optical and thermal. Their ability to operate at a wide range of temperatures, generally between -25°C and 85°C, makes them appropriate for a variety of applications. They are commonly used in the digital industry in items such as mobile phones to make touchscreen displays.
