RFVC6804 Application Field and Working Principle The RFVC6804 (Voltage Controlled Oscillator) is an integrated circuit found inRF Misc ICs and Modules. This particular IC is used as a voltage controlled oscillator which is suitable for voltage frequencies between 10 and 1000 MHz, making it ideal for applications such as cellular phones, DAMA modems, GPS receivers, and other consumer electronics. OverviewThe RFVC6804 is an integrated oscillator developed by RF Solutions. The device combines a voltage controlled oscillator and a temperature compensated reference circuit into a single, low-cost integrated circuit. It also includes a high-performance low-noise amplifier and power supply regulator. The reference circuit can output up to a maximum frequency of 1GHz, making it ideal for use in a wide range of applications. Applications The RFVC6804 is designed for applications requiring low-noise power supplies, high-frequency signals, temperature compensation and low-cost integrated circuit solutions. These applications include GPS receivers, cellular base stations, DAMA modems, access systems, ISM-band communications, and more. Additionally, because of its low cost and wide frequency range, the RFVC6804 is suitable for consumer electronics applications such as cellular phones, digital broadcast televisions, and wireless home networks. Working Principle The RFVC6804 is a closed-loop voltage-controlled oscillator (VCO) designed to generate very low phase noise signals. The oscillating frequency is controlled by an external voltage source. The oscillator output is determined by the capacitive loading, the inductive loading, and the circuit capacitance.The oscillator’s frequency is determined by the external components which are connected to the VCO. By varying the external components, the capacitance and inductance of the VCO can be adjusted to control the output frequency. The frequency can be changed by varying the oscillator’s potentiometer, or capacitive loading, or inductive loading, or the total capacitance of the portable circuit.The RFVC6804 is designed to operate at low-power levels and has low-noise performance. It has a frequency range of 10MHz to 1GHz and is capable of delivering a phase-noise performance of -150dBc/Hz at 10KHz offsets. The device can also provide a low phase noise signal at temperatures as low as -50°C. The RFVC6804 also includes a built-in temperature compensated reference circuit which ensures low-noise operation over a wide temperature range. The reference circuit includes a temperature compensation loop which ensures low-noise operation across a temperature range from -40°C to 85°C. ConclusionThe RFVC6804 is an integrated voltage controlled oscillator designed for low-noise, high-frequency applications. The device is ideal for a wide range of applications from cellular phones, access systems, and GPS receivers to digital broadcast televisions and wireless home networks. The integrated circuit includes a temperature compensated reference circuit which ensures low-noise operation across a wide temperature range. It also includes a low-noise amplifier and a power supply regulator. By varying external components, the capacitance and inductance of the VCO can be adjusted to control the output frequency.
