The so-called surface effect, that is, when the crystal is mechanically applied, will generate an electric field proportional to the pressure. A crystal with a magnetic effect, when subjected to an electrical signal, also undergoes an elastic deformation to emit a mechanical wave (sound wave), which can convert an electrical signal into an acoustic signal. Since this sound wave propagates only on the surface of the crystal, it is simply referred to as SAWF, and the surface acoustic wave filter has a small volume, light weight, reliable performance, and does not require complicated adjustment. A key component for implementing adjacent-frequency transmission in cable television systems. The surface acoustic wave filter is characterized by: (1) frequency response accuracy, non-perpendicularity is only ±0.3-±0.5 dB, group delay is ±30-±50 ns. (2) The SAWF has a good rectangular coefficient and an out-of-band rejection reachability of more than 40 dB. (3) Although the insertion loss is as high as 25-30dB, the amplifier can be used to compensate for the compensation loss. The surface acoustic wave filter includes a surface acoustic wave television image intermediate frequency filter, a television sound filter, and an electric video residual sideband filter.
