Descriptions:
Frequency multiplier is a circuit that allows the output signal frequency to be equal to an integer multiple of the input signal frequency. Input frequency is f1, then the output frequency is f0 = , this coefficient n is 2. Frequency multiplier has a wide range of applications, such as the transmitter frequency multiplier can make the main oscillator oscillation at a lower frequency to improve the frequency stability; frequency equipment uses frequency multiplier to increase the frequency offset; in the phase keying communication machine , The frequency multiplier is an important component of the carrier recovery circuit.
