SAW ResonatorsCrystals, oscillators, and resonators are electronic components that are used to generate precise frequencies and timing signals. These components are commonly used in electronic devices to provide a reference frequency for the operation of the device, such as in clocks, radio transmitters, and microcontrollers.
SAW resonators, or Surface Acoustic Wave resonators, are a type of resonator that uses a piezoelectric crystal as the resonant element. SAW resonators are similar to SAW oscillators, but they do not include the amplifying and feedback components that are needed to maintain a continuous oscillation. Instead, SAW resonators are used to filter or detect signals at a specific frequency, or to provide a reference frequency for other circuits. SAW resonators are commonly used in radio frequency (RF) applications, such as in wireless communication devices and RFID systems. They are highly stable and accurate, and can operate over a wide range of frequencies.
