Voltage Controlled Oscillators (VCOs) are electronic circuit components that are controlled by an applied voltage. VCOs are commonly used in a variety of applications, from audio and video equipment to communication systems and more. One example of a VCO is the VCO-119SMTTC, which is a type of integrated circuit (IC). It is primarily used to generate a sine wave carrier wave, which is a type of radio frequency (RF) signal.

The VCO-119SMTTC is a high-performance integrated circuit (IC) featuring a wide range of operating parameters. The circuit has a gain of 0.5 V/μs, a maximum output frequency of 1.2GHz, a supply voltage of 5 V, and an input impedance of 1.55 Ω. Additionally, it has a temperature compensated ramp waveform generator and an internal zero-phase-error loop.

In terms of its application field, the VCO-119SMTTC is used primarily in radio systems for generating output waveforms for transmission. It is also utilized in the generation of frequency-agile waveforms for spread-spectrum systems, as well as in various types of digital modulators, receivers, and test equipment. Furthermore, the VCO-119SMTTC can also be used in other applications requiring high-frequency sinusoidal signals, such as in electronic countermeasures systems, frequency synthesizers, and oscillators.

The working principle of a VCO-119SMTTC is based on the use of an voltage-controlled exponential current source. This current source is supplied with a current that is proportional to the applied voltage and is connected to pin 1 of the VCO-119SMTTC. When a voltage is applied to the current source, the current increases exponentially, generating an output waveform.

At the same time, this output waveform is fed into a capacitive divider, which is then connected to the output feedback pins (pins 3 and 4). When this output waveform is applied to the feedback pins, the output frequency is adjusted in proportion to the applied control voltage. The output waveform is further filtered, amplified, and modulated at the output pins of the VCO-119SMTTC.

Overall, the VCO-119SMTTC is an integrated circuit (IC) designed specifically for generating sinusoidal waveforms for radio frequency and electronic countermeasures systems. Its working principle relies on the use of a voltage-controlled exponential current source, which is used to generate an output waveform that is then fed into a capacitive divider. This waveform is further amplified and modulated at the output pins of the VCO-119SMTTC, allowing it to be used in a variety of radio frequency and other applications requiring high-frequency waveforms.
