Description

technical field [0001] The invention relates to the field of electronics, in particular to a high frequency multiplier based on a pulse amplification trigger circuit. 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 is prone to generate false trigger signals during work, which makes the output signal of the frequency multiplier unstable and cannot meet people's needs.
