Oscillators

An oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices from clock generators, timers and voltage controlled oscillators (VCO) to modulation and demodulation circuitry within radio transmitters and receivers. One of the most common applications of oscillators is the SIT9120AI-1C2-33E25.000000T, a voltage-controlled oscillator (VCO).

SIT9120AI-1C2-33E25.000000T Application Field and Working Principle

The SIT9120AI-1C2-33E25.000000T is a voltage-controlled oscillator (VCO) that is used to generate precise frequencies up to 33.25GHz. It is designed to deliver the best performance and phase noise when used in applications such as systems requiring ultra-low phase noise, including phased array radar, wireless infrastructure, active antenna, Point to Point (P2P) and Point to Multi-Point (P2MP). This oscillator operates over a temperature range of -40 to +85 ℃ while maintaining a wide tuning range from 0.7 to 8.2GHz. It also offers excellent suppression of spurs and is very linear over temperature and supply voltage.

The working principle of the SIT9120AI-1C2-33E25.000000T is based on the fact that the oscillation frequency of a VCO is determined by the applied voltage. The frequency of oscillation is determined by the time-constant of a charging and discharging capacitor. When no voltage is applied to the input of the VCO, the oscillation frequency is at its lowest (typically around 10MHz). When a voltage is applied to the input of the VCO, the frequency of oscillation is increased. The frequency is dependant on the magnitude of the applied voltage and the type of VCO used. In the SIT9120AI-1C2-33E25.000000T, the frequency is increased up to 33.25GHz.

The SIT9120AI-1C2-33E25.000000T is an ideal choice for applications requiring ultra-low phase noise as it offers excellent suppression of spurs and a high signal stability. It also features a wide tuning range from 0.7 to 8.2GHz and operates over a temperature range of -40 to +85 °C, making it an ideal choice for many applications.
