An oscillator is a device that produces an output signal at a certain frequency independent of the input power. The most common type of oscillator is the oscillating electrical circuit, which uses the principles of electromagnetic induction to generate a high frequency alternating current output. The 655V156E3C3T is a type of class C oscillator, which uses an inductor-capacitor (L-C) tuned circuit to produce the frequency-dependent output.

Application Field

The 655V156E3C3T is primarily used in radio frequency (RF) communication systems such as base station and cell phone systems. It can also be used in civil and military radar systems, navigation systems, guidance systems, and medical instrumentation. The relatively wide bandwidth of the 655V156E3C3T makes it an ideal choice for these applications, as it is capable of generating stable frequency signals over a wide range of frequencies.

Working Principle

The 655V156E3C3T works on a basic oscillating circuit principle. It consists of an inductor (L) connected in series to a capacitor (C) and a feedback resistor (R). When a direct current (DC) power supply is connected to this circuit, current will start to flow from the DC source, and through the inductor and capacitor. The inductor will store energy in the form of a magnetic field, while the capacitor will store energy in the form of an electric field. As the current flows through the inductor, the voltage across it will increase, and as it flows through the capacitor, the voltage across it will decrease. Eventually, the inductor will reach a peak in voltage, and the capacitor will reach a peak in current. At this point the current will reverse direction, and the voltage across the inductor will decrease, while the voltage across the capacitor will increase. As the current continues to alternate, a continuous electrical signal is produced by the circuit. The signal frequency is determined by the inductance and capacitance of the components in the circuit.

Furthermore, the 655V156E3C3T has an output amplifier which receives the generated signal to increase the signal level and provide the necessary current to drive the output hardware. In addition, a feedback loop is also used to prevent the oscillator from drifting at high frequencies. This feedback loop consists of the feedback resistor (R) and is connected directly from the output back to the input of the oscillator. The value of the feedback resistor is set by the manufacturer to maintain the desired frequency and phase stability.

In summary, the 655V156E3C3T is a type of class C oscillator capable of generating stable frequency signals over a wide range of frequencies. Its application field includes radio frequency applications, radar systems, navigation systems, guidance systems, and medical instrumentation. It functions by using an inductor-capacitor (L-C) tuned circuit to generate a frequency-dependent output, and an output amplifier and feedback loop to ensure phase and frequency stability.
