Surface Acoustic Wave Oscillators are specialty microcircuits that process analog signals that occur in radar, communications, electronic warfare, and other defense/space situations. SAW Oscillators are different from other oscillator types in that they use acoustic waves on a material's surface for signal processing. A SAW Oscillator contains an input transducer that converts electric signals into acoustic waves and an output transducer that reconverts these waves into electrical signals. Surface Acoustic Waves travel through a piezoelectric substrate between the input and output transducers, which lends SAW Oscillators great flexibility to achieve wide ranges of signal processing functions.
SAW filters offer reduced size, weight and cost compared to other filter technologies. One can use SAW filter solutions for narrowband, GPS band applications, standard IF and, standard RF bands. SAW Filters come in semi-standard and custom designs to suit different end-users' needs.
SAW Delay Lines
A SAW Delay Line is the basic element of a SAW sensor. Various kinds of piezoelectric substrates such as quartz, lithium tantalate, and lithium niobate are used to make the lines. SAW Delay Lines come in different packaging options such as ceramic leadless chip carriers, which provide small size and weight, and platform packages, which are suited for harsh applications.
