ECS-3518-040-B-TR

Oscillators are components in electronic systems, serving many purposes which can range from providing timing signals, to acting as a reference for frequency select circuits. One example of an oscillator is the ECS-3518-040-B-TR, which is made from an insulated gate bipolar transistor oscillator die, providing high stability and low phase noise.

ECS-3518-040-B-TR Application Field and Working Principle

The primary application field for the ECS-3518-040-B-TR is frequency control in systems such as communication systems, test and measurement equipment, and radar systems. It works on the principle of an insulated gate bipolar transistor (IGBT) oscillator, which combines the simple structure and fast commutation characteristics of any bipolar transistor with the added benefit of voltage control from an insulated gate. The ECS-3518-040-B-TR is able to provide a higher output voltage and good temperature stability, as well as low power consumption.

At the heart of the ECS-3518-040-B-TR is the IGBT oscillator; the basic functions are controlled by two capacitors, two resistors and an IGBT transistor. When forward biased, the transistor allows current to flow through its gate-emitter junction, and this process is kept in a negative feedback loop by the two capacitors, which store and release energy. This process is repeated and the repetition rate is dependent upon the value of the two resistors. As the output voltage reaches the zero-crossing point, the IGBT and the two capacitors reverse their roles, and the circuit repeats the cycle.

The ECS-3518-040-B-TR is highly efficient, providing a high output voltage of 54 dBc, and a low phase noise of below -110 dBc/Hz @10 kHz offset. It is also able to operate in temperatures ranging from -40 to +85 degrees Celsius, while consuming only 4 mW of power making it ideal for applications requiring a low power, highly efficient oscillator. The ECS-3518-040-B-TR is available in a ceramic surface mount package and is suitable for a wide variety of applications.

In summary, the ECS-3518-040-B-TR is an IGBT oscillator, which provides a stable output voltage in addition to low phase noise, high temperature stability, and low power consumption. These features make this oscillator suitable for use in communication systems, test and measurement equipment, and radar systems.
