Signal frequency multiplication amplification device based on super-harmonic and synchronous resonance combination

Abstract

The invention relates to a signal frequency multiplication amplification device based on super-harmonic and synchronous resonance combination. The device comprises an electrostatic excitation vibration device and a super-harmonic synchronous resonance frequency multiplication signal extraction device. The electrostatic excitation vibration device of a cantilever beam is composed of a low-frequencymicro beam, a fixed end, an electrostatic driving electrode, a base, a direct-current voltage power supply, a signal source and a wire. The super-harmonic synchronous resonance frequency multiplication signal extraction device is composed of a low-frequency micro beam, a fixed end, a high-frequency micro beam, a signal acquisition sensor, a coupling connection block and a wire. An alternating current signal is subjected to super-harmonic and synchronous combined resonance to generate harmonic vibration with the excitation frequency being 3N times, so that frequency-doubled vibration of super-harmonic synchronous resonance is achieved; a signal acquisition sensor acquires a frequency multiplication vibration signal, and a frequency multiplication vibration signal is filtered by a band-passfilter to generate a high-frequency frequency multiplication signal.

Problems solved by technology

However, the vacuum electronics signal source has problems such as large volume and high driving voltage; the non-linear circuit of semiconductor electronics generates power series signals, and there are problems such as dense intermodulation signals leading to filtering difficulties and low signal-to-noise ratio due to energy dispersion

In addition, the above signal sources are easily interfered. For example, the signal of a mobile phone will cause the loss of the GPS signal of a civil aviation airliner, and radio interference can trap drones, etc.
