Working Principle

The working principle of the SMV1235-001 is based on the capacitance between the two electrodes of the diode. This capacitance is controlled by the voltage applied to the two electrodes, with a higher voltage resulting in a greater capacitance. As the frequency of the applied signal is changed, the capacitance of the diode will also change, resulting in a continuously variable frequency output. This is done by varying the voltage across the two electrodes, either manually or by an external control voltage.
