Description
technical field [0001] The invention relates to the field of electronics, in particular to a simple frequency multiplier. Background technique [0002] A frequency multiplier is a circuit that makes the output signal frequency equal to an integer multiple of the input signal frequency. With the continuous development of electronic technology, frequency multipliers are used more and more widely. For example, the transmitter can make the main oscillator oscillate at a lower frequency to improve frequency stability; Large frequency offset; in the phase keying communication machine, the frequency multiplier is an important component of the carrier recovery circuit. However, the currently used frequency multiplier circuit is complex, which makes its manufacturing cost too high. Contents of the invention [0003] The purpose of the present invention is to overcome the defect of complex circuits of the current frequency multiplier and provide a simple frequency multiplier with ...
