      Surface-Acoustic-Wave Filter

      • Surface-Acoustic-Wave Filter
      Purpose

      Bandpass filtering of high-frequency electrical signals.

      Scope

      Receiving and transmitting paths of high-frequency devices (radars, communication systems, etc.)

      Principle of Operation

      The SAW filter features an input and output. The source signal is supplied to the input, the filter uses it to cut out a certain frequency band, after the filtered signal is provided to the output. The filtration is performed by converting an electrical signal into an acoustic wave and after passing the filter elements back into an electrical signal.

      Benefits
      • Low overall dimensions (2-3 orders of magnitude smaller compared to electromagnetic analogues)
      • High temperature stability
      • Wide operating frequency range (1.0 MHz – 3 GHz)
      • Low insertion loss of 1.0-3.0 dB at bandwidths 1-3%
      • High reliability
      • Repeatability of parameters and low cost in serial production
