Crystal Filter is an electronic component used for filtering and selecting specific frequencies. It uses the characteristics of crystals to achieve efficient filtering effects. The principle of the crystal filter is to use the nonlinear characteristics of the transistor to divide the input signal into different frequency bands, and then filter out unwanted signals through selective amplification and suppression. Its advantages are high precision and high stability, and it is suitable for high-demand electronic systems. HCI provides crystal filters of different package sizes in the 7~60MHz range, which are widely used in wireless communications, computer systems, audio systems, and other fields. It can achieve efficient signal filtering and suppress spurious interference.
