Oscillators

As discussed previously, oscillators are electronic components which generate repeating periodic signals. SIT1602BC-12-30N-38.000000G is a type of voltage-controlled oscillator (VCO) with phase shift (PS) technology, used in high-frequency microwave applications.

Applications

The SIT1602BC-12-30N-38.000000G is typically used in wireless communication applications, including point-to-point, point-to-multi-point, 2G/3G/4G applications, digital networking and more. It is also used in commercial and military radar systems, satellite radio and other High Freequency (HF) applications. Additionally, the VCO is often used as part of a wide range of switching or timing solutions.

Working Principle

The SIT1602BC-12-30N-38.000000G VCO operates based on a common principle for voltage-controlled oscillators. Namely, the frequency of the output signal is inversely proportional to the control voltage. This is achieved through the use of a feedback loop and a voltage-controlled frequency multiplier circuit. The VCO can be tuned to output frequencies between the range of 10 kHz to 30 GHz.

The VCO features an oscillator core, amplifier, phase shifter and loop filter. The oscillator core produces a sinusoidal signal, which is then amplified, and the resulting signal is then applied to the phase shifter. The phase shifter delays the phase of the signal as determined by the control voltage applied. The output signal from the phase shifter is then fed back to the oscillator core and loop filter, forming a continuous feedback loop. If the control voltage is increased, the output frequency decreases in response and vice-versa.

The loop filter of a VCO is a passive electrical filter, such as a resistor and capacitor (RC) filter, used to control the frequency stability of the oscillator. The filter is essential in maintaining stability of the output frequency, especially in noisy environments. It acts to reduce the amount of noise entering the feedback loop, allowing for a more accurate output signal.

Summary

The SIT1602BC-12-30N-38.000000G VCO is a voltage-controlled oscillator designed for use in high-frequency microwave applications. With a voltage control range of 10 kHz to 30 GHz, the VCO is suitable for use in a variety of applications including wireless communication, digital networking, commercial and military radar systems and satellite radio. The VCO is based on a feedback loop and voltage-controlled frequency multiplier circuit, and a loop filter is used for enhanced frequency stability. This makes the VCO ideal for applications where accuracy and precision are of critical importance.
