Voltage Controlled Oscillators (VCOs) are widely used as important components in radio frequency (RF), microwave, and wireless communication systems. The CVCO55CC-3345-3955 is an amplifier-based voltage controlled oscillator designed and manufactured by Crystek Corporation.

The CVCO55CC-3345-3955 features excellent phase noise performance and low spurious over a wide frequency range, making it the ideal choice for applications such as RF test instrumentation, cellular base station transceivers, global positioning systems, satellite broadcast, wireless communications, and broadband data transmission. This VCO also offers unparalleled stability and repeatability.

The majority of VCOs are constructed using an amplifying stage driven by an RC (resistor–capacitor) network. The CVCO55CC-3345-3955 is no exception; it is implemented using an amplifier whose output is fed to a controlling element, typically a varactor (or reverse-biased diode) whose capacitance is controlled by an external voltage. This voltage is used to adjust the output frequency of the oscillator over a wide range, typically from one to several hundred MHz.

The CVCO55CC-3345-3955 consists of a high-gain amplifier whose output is connected to a feedback circuit. The feedback circuit includes a voltage-controlled capacitor, usually implemented using a varactor, which is connected to the input of the amplifier. As the externally applied voltage to the varactor is varied, the capacitance of the device is adjusted, causing a change in the frequency of oscillation of the oscillator. The output frequency of the oscillator is thus linearly dependent on the externally applied voltage.

The CVCO55CC-3345-3955 is designed to provide excellent phase-noise performance and spurious suppression over a wide frequency range. It has very low distortion, low noise, and low jitter. The exceptional linearity and temperature stability of the device further provides a clean and stable output waveform. The device is also designed to have high stability over a wide temperature range and can operate over a wide supply voltage range.

The CVCO55CC-3345-3955 is an ideal choice for applications such as RF test instrumentation, cellular base station transceivers, global positioning systems, satellite broadcast, wireless communications, and broadband data transmission. It is also ideal for point-to-point and point-to-multipoint radio applications. With its low noise and exceptional stability, the CVCO55CC-3345-3955 is well-suited for use in any system requiring precise control of frequency.
