Introduction
Voltage controlled oscillators (VCOs) are widely used in communication and control systems. VCOs have the characteristics of low phase noise, wide bandwidth, low supply voltage and good linearity. They are also suitable for a variety of operating temperature ranges, making them ideal for applications such as phase-locked loops, frequency synthesizers, and modulators. In this article, we will discuss the CVCO55CC-4267-4442 VCO, its application field and working principle.Application Field
CVCO55CC-4267-4442 Voltage Controlled Oscillator is a wideband, low noise, low phase noise and wide tuning range voltage controlled oscillator. It is designed for use in a variety of applications in the very high frequency range, covering frequency ranges from 4.3 GHz to 7.8 GHz. It can be used in applications such as frequency synthesizers, spectrum analyzers, test instrumentation, RF communication systems, radar systems and point-to-point microwave links.Working Principle
Voltage controlled oscillators (VCOs) are made up of two basic components: an oscillator and a frequency control element. The CVCO55CC-4267-4442 VCO is based on a Gilbert-Miller circuit topology; this circuit contains two transistors, two capacitors and two resistors. The signal at the output of the VCO is proportional to the voltage applied to the input. The frequency of oscillation is determined by the capacitors used in the circuit. The CVCO55CC-4267-4442 VCO has an operating range of 4.3 GHz to 7.8 GHz with a tuning sensitivity of 10 MHz/V.The circuit diagram of the CVCO55CC-4267-4442 is shown in figure 1. The circuit is composed of a Gilbert-Miller stage, with two transistors connected in a cross-coupled fashion to form an emitter-coupled pair, followed by an emitter-follower output stage with a differential collector load. The core of the VCO is the Gilbert-Miller stage, with inductors L1 and L2 acting as stray inductances to provide the non-linearity necessary for the VCO to oscillate at its resonance frequency. The two capacitors, C1 and C2, determine the frequency of oscillation, and can be varied in value to change the operating frequency. The two resistors, R1 and R2, are connected to the base of each transistor and act to provide current limiting in the circuit.Conclusion
The CVCO55CC-4267-4442 voltage controlled oscillator is a wideband, low noise, low phase noise, and wide tuning range voltage controlled oscillator, designed for use in a variety of applications in the very high frequency range. It is based on a Gilbert-Miller topology, and consists of an oscillator and a frequency control element. Its frequency of oscillation is determined by the capacitors used in the circuit, while the two resistors provide current limiting in the circuit. This makes the CVCO55CC-4267-4442 an ideal choice for applications such as frequency synthesizers, spectrum analyzers, test instrumentation, RF communication systems, radar systems and point-to-point microwave links.The specific data is subject to PDF, and the above content is for reference
