Applications of point contact diode

The point contact diodes are certainly continued to be of great importance of some time to come. Some of their characteristics are very desirable for certain applications. There are some important applications of point contact diode which are given below,

• The point contact diode is used in pulse circuits.
• It is used as a video detector in television receiver.
• It is used in microwave frequency mixer circuits.
• It is used in non linear i.e. rectifying elements of R.F. (radio frequency) signal detection.
• It is used as an AM (amplitude modulation) detector in radio receiver.
• It is used in frequency conversation circuits.
• It is used in high frequency circuits of the order of 10 GH_Z or more.
