VCOs (Voltage Controlled Oscillators) are essential in the development and operation of many electronic systems. They are widely used to generate or oscillate RF or microwave signals, or to lock a system to an external reference frequency. VCOs tend to cover a wide range of fields, from telecommunications to automation and industrial control, as well as low power, high-end military applications.

The VCO-114TC is an example of a voltage-controlled oscillator. It is highly compact, operates from 8 to 18 Volts DC, and consumes very little power. It is designed for applications such as sensor switches, digital control systems, RF remote controls, and RF telemetry. The VCO-114TC is a reliable, low-cost solution for achieving accurate phase lock to an RF signal within the same frequency band.

The working principle of the VCO-114TC is relatively straightforward. A voltage-controlled oscillator (VCO) is an electronic oscillator whose frequency can be accurately adjusted or controlled by a voltage input. When the voltage is adjusted, the output frequency of the oscillator will also adjust. This process is known as voltage-controlled frequency tuning, and is the basis of the VCO-114TC.

The VCO-114TC is built upon a planar diode-ring oscillator circuit design. The diode-ring oscillator is comprised of an inverting amplifier, feedback diodes, a frequency-determining capacitance, and a controlling voltage. The controlling voltage is usually provided by a voltage-controlled voltage source, such as a digital-analog converter (DAC).

When the voltage-controlled voltage source is adjusted by the DAC, the controlling voltage on the oscillator will also adjust accordingly. This voltage adjustment causes a change in the oscillator frequency. This change in frequency is known as frequency tuning. The output frequency range of the VCO-114TC is typicially between 200 and 465 MHz, depending on the supply voltage.

The VCO-114TC also features frequency-stability compensation circuitry, which can virtually eliminate temperature-dependent frequency shifts. The compensation circuitry helps ensure that the output frequency remains accurate, even under changing temperature and supply voltage conditions.

The VCO-114TC is a low-cost, reliable, and highly accurate device for generating or oscillating RF or microwave signals. It is widely used in many different applications, such as telecom, automation, industrial control, and even low-power, high-end military systems.
