Oscillators, which play a key role in communication signal processing, are widely used in radio transmitters, microwave communication systems, and signal-simulated circuits. In this article, we will discuss the EG-2021CA 150.0000M-CGRNB, a voltage-controlled oscillator (VCO), which is a type of oscillator widely employed in frequency synthesizers and phase locked loops. We\'ll explain its application field, structure and working principle in detail.

Application Field of EG-2021CA 150.0000M-CGRNB

The EG-2021CA 150.0000M-CGRNB VCO is applicable to a wide range of frequency synthesizers and phase locked loops. These devices are widely used in militaryradar and microwave communication, which require frequency stability and precision. The EG-2021CA 150.0000M-CGRNB is also used in mobile communication, including Network signalling, Telecom signals and Wireless systems. The VCO is also suitable for other fields such as audio, video and instrumentation control systems.

Structure of EG-2021CA 150.0000M-CGRNB

The EG-2021CA 150.0000M-CGRNB is a quartz crystal-based voltage-controlled oscillator operating with a fixed 15.0000 MHz frequency and a variable voltage-controlled frequency of up to max 900.000MHz. The device comprises an external quartz crystal, a voltage-controlled gain block, an output buffer and a power supply. The external quartz crystal is an HTC resonator of 15.0000MHz, providing the initial frequency with high precision and low noise. The voltage-controlled gain block consists of a gain-controlled element and its associated electronic circuitry. This is a silicon-based component, with the gain controlled by an external voltage. The gain is a direct function of the voltage applied. The output buffer is a low-noise, high-gain amplifier providing the output signal at a much higher voltage than the input signal. This stage is also referred to as voltage amplification. The power supply is an external voltage source. The external voltage source provides the necessary supply voltage for the operation of the device. The device can operate at a supply voltage between 3 and 15V.

Working Principle of EG-2021CA 150.0000M-CGRNB

The EG-2021CA 150.0000M-CGRNB operates on the principle of voltage-control frequency control. The device is driven by an external voltage-controlled oscillator and an external quartz crystal. When a signal is applied to the voltage-controlled oscillator, the voltage changes the value of the gain in the gain-controlled element, thus changing the oscillation frequency of the device.The output buffer produces high-voltage output signal, which can be used in a variety of applications. When the working frequency of the device is adjusted to the resonant frequency of the external quartz crystal, the output frequency is stabilized and the device will run at that frequency with high accuracy and low phase noise. This increases the frequency stability of the device, allowing for precise tuning and frequency synthesis. In conclusion, the EG-2021CA 150.0000M-CGRNB is a quartz crystal-based voltage-controlled oscillator with wide application field. This device is suitable for use in radio transmitters, microwave communication systems and signal-simulated circuits, due to its wide frequency tuning range and high frequency stability. The device is driven by an external voltage-controlled oscillator and an external quartz crystal, thus providing frequency stability and precision.
