Oscillators – 7W-15.000MBD-T Application Field and Working Principle

Oscillators are an important type of electronic circuits usually consisting of an amplifier and an actively connected feedback circuit. They are designed to generate an output signal with a stable frequency. Oscillators of this type are essential to most of today\'s electronic applications in communications, power electronics and digital control systems, and they are widely used for demonstrations and experiments in educational and lab environment.The 7W-15.000MBD-T oscillator is a type of microwave oscillator used to generate stable frequencies in the microwave (GHz) range. It is used in a variety of applications such as specialized communications, antenna systems, radar systems, satellite systems, and other areas of high frequency engineering. The 7W-15.000MBD-T oscillator is available in two different versions, a vertical polarization (V1) and a horizontal polarization (H1) version. The 7W-15.000 MBD-T oscillator consists of a quartz crystal resonator connected to a transistor amplifier. A differentiator is used to prevent the amplifier from saturating. The amplifier and the resonator form a negative feedback loop which resonates at a particular frequency. This frequency is determined by the characteristics of the quartz crystal resonator. The 7W-15.000 MBD-T oscillator has an output power up to 7W and a frequency range of 7MHz to 15.000 MHz.The working principle of the 7W-15.000MBD-T oscillator can be explained using the Colpitts configuration. In this topology, a quartz crystal resonator is connected between the collector and the base of a BJT transistor. The capacitor in series and the capacitor in parallel provide the negative feedback loop which produces an oscillation. The frequency of the oscillation is determined by the resonance frequency of the quartz crystal resonator. The transistor amplifier takes the input signal from the quartz crystal resonator, amplifies it and sends it back to the resonator. This creates a self-sustaining oscillation at the crystal’s resonant frequency. The output of the amplifier is coupled to the antenna or connected device.The 7W-15.000MBD-T oscillator is widely used in high frequency applications such as satellite communication systems, global navigation systems, UAV systems, broadcasting, cellular, and navigation.
