Our range of SAW filters is used in applications such as automotive electronics and telematics, remote control, Bluetooth, WLAN, mobile phones, IoT and many others.Surface Acoustic Wave Filters or SAW Filters are compact, low-cost RF filters that can be used in a wide range of applications up to 3 GHz. SAW filters operate by converting electrical energy into acoustic or mechanical energy on a piezoelectric material. To do so these filters uses interdigital transducers (IDTs). The IDTs have interleaved metal electrodes on either end of the device which converts an electrical signal into an acoustic wave and then back to an electrical signal.Once the electrical energy is converted into acoustic waves, the waves travel across the surface of an elastic, piezoelectric material with an amplitude decaying into the substrate material, such as quartz, lithium tantalite (LiTaO3) or lithium niobate (LiNbO3). This decay is what causes the insertion loss in SAW Filters.

What are SAW filters used for?

SAW filters are used to filter out desired frequencies. For example, they are widely used in mobile phones to filter both RF and IF frequencies,SAW filters play an important role in suppressing high-order harmonics, image information, emission of leaked signals, and various parasitic clutter interference of electronic information equipment, and can achieve filtering of amplitude-frequency and phase-frequency characteristics with any required precision. This is difficult to accomplish with other filters.

What are the different types of SAW filters?

There are many different types of SAW filters. Examples include IF SAW filters, CDMA SAW filters, wideband SAW filters, and piezoelectric SAW filters. An IF SAW filter uses an intermediate frequency (IF) and suitable for many third-generation (3G) base station equipment protocols. A CDMA SAW filter is based on code division multiple access (CDMA) technology.CDMA SAW filters are used in mobile phones which operate in the frequency band of 800 MHz and 1.9 GHz. A wideband SAW filter is a high-frequency filter that is capable of providing high stability. A piezoelectric SAW filter consists of two inter-digital transducers (which are mounted on a piezoelectric substrate. Other SAW filters are commonly available.
