Oscillators are electrical circuits that generate a periodic signal, usually in the form of a sine wave. The DSC1121DE1-025.0012 is a Compact, precision, micromachined, voltage controlled oscillator (VCO) designed for use in cellular telecommunication and microwave systems. It features a wide tuning range and low phase noise.

The DSC1121DE1-025.0012 provides a very wide tuning range of 19.2 MHz to 40.5364 GHz, primarily determined by the external RF output matching components. The oscillator itself is a precision micromachined design, incorporating a high quality oscillator cell made with a proprietary thin film layer process. This allows the oscillator to have very low phase noise of -118 dBc/Hz at 10 kHz offset.

As a result of its high frequency range and good noise performance, the DSC1121DE1-025.0012 can be used in a variety of applications, including transceivers, tuners, radio links, receivers, and more. Its small size and low power consumption make it well suited for mobile and battery-powered applications.

The DSC1121DE1-025.0012 is built around an oscillator core, typically designed in bipolar technology, which uses a capacitor as a frequency-determining element. The oscillator is biased with a DC voltage, and when fed with an AC voltage, changes its frequency. The AC voltage source is usually a voltage controlled oscillator (VCO), which is connected to the oscillator\'s input and provides the necessary control voltage.

The output of the DSC1121DE1-025.0012 is then amplified and then coupled to the system. It is designed to operate over a wide supply voltage range (2.3V to 5V), and over a wide temperature range (-20°C to +85°C). Its low voltage performance allows for a cost-effective solution offering excellent phase noise and low power consumption.

The DSC1121DE1-025.0012 is a versatile, high performance VCO offering excellent performance in many different applications. It is ideal for use in a variety of communications networks, including cellular, microwave, Wi-Fi, and GPS applications. Its wide tuning range, low phase noise, and high linearity make it an attractive option for demanding applications.
