Intermediate frequency (I.F.) crystals
International Crystal Manufacturing (ICM) manufactures a wide selection of tight tolerance high quality Intermediate Frequency (I.F.) crystals. I.F. crystals, also known as L.O. Crystals (Local Oscillator Crystals), Mixer Crystals or Oscillator Crystals, are used in superheterodyne receivers to help create a constant frequency called the Intermediate Frequency or IF. Often over looked tight tolerance high quality I.F. crystals can improve overall stability of the receiver.
