Phase Locked Voltage Controlled Oscillators

Phase Locked Voltage Controlled Oscillators, is a type of frequency synthesizer that uses a phase-locked loop to lock the output frequency to a reference signal. The voltage-controlled oscillator (VCO) is used to generate the output frequency, while the phase-locked loop (PLL) is used to control the phase and frequency of the output signal.

Its characteristics include:

1. High frequency stability:
PLVCO has very high frequency stability, with a phase-locked loop that can eliminate phase changes and noise interference in the input signal, resulting in higher frequency stability of the output.
2. Wide frequency adjustable range:
PLVCO has a wide frequency adjustable range, and the output frequency can be adjusted within a certain range by controlling the voltage.
3. Low phase noise:
PLVCO has very low phase noise, making it suitable for applications with high phase requirements, such as communication, radar, and other fields.
4. Strong noise resistance:
PLVCO has strong noise resistance and can achieve reliable frequency stable output in high noise environments.
5. Excellent fast performance:
When the input signal frequency or phase changes, PLVCO has a very fast response speed and can quickly track input signal changes; At the same time, its output signal also has a high rise and fall time, suitable for fast switching applications.
6. Small size and low power consumption:
PLVCO has a very high integration level, small size, and can be used in small electronic devices. At the same time, its power consumption is also very low, suitable for battery powered systems.

Application:

1. PLL network: PLVCO can be used to generate reference signals in PLL (Phase Locked Loop) networks.
2. Communication system: PLVCO is widely used in various communication systems, such as digital television, modems, and radio transceivers.
3. Test and measurement: PLVCO can be used in various test and measurement equipment, such as spectrum analyzer, frequency meter and frequency standard.
4. Radar: PLVCO can be used in various radar systems, such as high-frequency radar, ground penetrating radar, and weather radar.
5. Navigation: PLVCO can be applied to various navigation systems, including GPS, GLONASS, Beidou, and Galileo.

Qualwave supplies low phase noise PLVCO at frequencies up to 32 GHz.
