Voltage Controlled Oscillators (VCOs)

Voltage controlled oscillators (VCOs) are widely used in a variety of application fields, such as radio communication, digital signal processing and general time-based circuits. VCOs typically have a frequency-to-voltage response that is linear, allowing for the convenient control of frequency and phase using simple, low-cost components. The UMS-800-A16-G is one example of such a VCO and is used in a range of applications.The UMS-800-A16-G is a frequency-agile device specifically designed for use in applications where an adjustable frequency range is required. It is a voltage controlled oscillator that can generate signals across a wide frequency range of 15Hz to 8MHz, with a very fast tunability of 5kHz or less. It also has very low power consumption, making it suitable for use in portable applications.The UMS-800-A16-G oscillator is a two stage device that combines a voltage-controlled oscillator (VCO) with a phase frequency detector to create an integrated solution. The VCO contains a varactor diode, which is a diode having a voltage-variable capacitance that responds to a control voltage. This allows the VCO to control the frequency of its output signal. A phase frequency detector is also used to detect any phase difference between the input reference signal and the output signal of the VCO. The output of the phase frequency detector is then used to adjust the VCO\'s output frequency, ensuring that the output signal accurately follows the reference signal.In operation, a reference signal is provided to the phase frequency detector. This reference signal is generally provided by external circuitry but can also be generated internally. The phase detector monitors the phase difference between this reference signal and the output of the VCO, and adjusts the control voltage provided to its varactor diode. This results in the output frequency of the VCO following the reference signal.The UMS-800-A16-G is a highly stable and reliable device due to its advanced temperature compensation techniques. It has an excellent phase noise performance, with a typical figure of 40dB down at 100kHz offset, making it ideal for applications where low noise is required. The accuracy of the UMS-800-A16-G is also very high, with typical temperatures stability of 0.015%/°C and typical frequency modulation accuracy of 0.05%.Overall, the UMS-800-A16-G is an excellent choice for applications that require a wide frequency range, fast tunability and low power consumption. Its high stability, accuracy and excellent phase noise performance makes it a great choice for a variety of applications.
