CVCO55CC-2140-2140

Voltage Controlled Oscillators (VCOs), are the key building blocks of modern communication systems. The performance of a VCO is determined by its frequency tuning range, linearity, and pull-in range. The CVCO55CC-2140-2140 is one such oscillator, and this article outlines the application field and working principles of this device.

The CVCO55CC-2140-2140 is a high performance VCO specifically designed for use in wireless applications. This voltage controlled oscillator is designed particularly for high frequency applications, and its tunable frequency range ranges from 830 MHz to 850 MHz. It has a supply voltage of 2.9V to 5.5V, and a minimum atomization of 2.75V. The VCO’s primary benefit is its low power consumption of 7mA typical current consumption, with a maximum of 20mA. This allows for easy integration of the component into low power, mixed signal, and high frequencies systems.

The CVCO55CC-2140-2140 also offers exceptional linearity, which is important for modulation and demodulation performance in communication systems. This is because it provides a minimum of 12dBm linearity over the full tuning range. Additionally, its pull-in range of 0.02% is approximately twice that of conventional VCOs, and its extra wide stop band of -75dBc helps to reduce phase noise interference during transmission. It also has an operational phase noise of -108dBc/Hz at 10kHz offset, ensuring reliable operation in wireless communication systems.

The operating principle of the CVCO55CC-2140-2140 is based on the use of negative resistance characteristics of a FET oscillator, combined with voltage tuning capabilities. It has an integrated frequency synthesizer to maintain its frequency output when the voltage is changed. The input voltage is tuned to set the oscillator to a particular frequency. This is achieved by a comparator circuit that monitors the generated frequency and constantly resets the oscillator until it is matched with the reference frequency.

The CVCO55CC-2140-2140 is recommended for use in RF applications such as wideband receivers, radio repeaters, radio base stations, GSM, GPRS, 802.11a/b/g, WiMAX, and 3G/4G LTE applications. It is the ideal choice for high-speed and long-range communication systems, due to its exceptional frequency stability and low power consumption. It is also suitable for applications where low radiation is required, given its low radiation efficiency. The VCO can be also used in other consumer electronics such as portable media players, as well as radio clocks and consumer radio frequency modules.

In summary, the CVCO55CC-2140-2140 is an advanced high performance VCO that can be used in a wide range of wireless communication applications. Its outstanding performance characteristics, such as frequency tuning range, linearity and pull-in-range make it an ideal choice for applications requiting low power consumption, radiation efficiency, and frequency stability.
