The function of high-frequency oscillator is to convert direct current energy into alternating current energy with a certain frequency.
A high-frequency oscillator is a circuit that generates high-frequency signals. It usually consists of an oscillation loop and an amplifier. Oscillating circuit is the core component to generate high-frequency signal, which can convert DC power supply into high-frequency AC signal.
generally speaking, the oscillation loop of a high-frequency oscillator consists of one or more resonant circuits. The resonant circuit includes inductance, capacitance and crystal, which constitute a * * * vibration circuit. When the * * * oscillation circuit is externally excited, * * oscillation will occur, thus generating high-frequency oscillation signals in the circuit.
the high-frequency signal generated by the oscillating circuit is usually very weak and needs to be amplified by an amplifier before it can be output to the external circuit. Amplifier is usually composed of semiconductor devices such as transistors and field effect transistors, which can amplify the weak signal generated by the oscillating circuit to a sufficient level for supply to external circuits.
