Introduction

Oscillators are electronic circuits that produce a repetitive or oscillatory electronic signal. They come in a wide variety of types, ranging from simple square wave oscillators to complex phase-locked loops. One of the more commonly used oscillators is the EG-2102CA 156.2500M-LGPAL0 oscillator. This article will discuss the application field and working principle of the EG-2102CA 156.2500M-LGPAL0 oscillator.

Application Fields

The EG-2102CA 156.2500M-LGPAL0 oscillator is commonly used in telecommunications and radio frequency (RF) applications. It has the capacity to operate at a frequency range of 156.2500MHz - 156.9500MHz and has a good level of phase noise at less than -118dBc/Hz. Its response time is also quite good, with a turn-on time of less than 100ns and a turn-off time of less than 50ns.The EG-2102CA 156.2500M-LGPAL0 oscillator is often used as an oscillator for local oscillators (LO), frequency synthesizers, and transceivers. It is also used in other equipment such as radar systems, satellite communications, and cellular and cordless phones.

Working Principle

The EG-2102CA 156.2500M-LGPAL0 oscillator uses a negative resistance oscillator circuit. This circuit consists of an active device (typically an amplifier) coupled with an inductor and capacitor. The combination of the inductor and capacitor in a closed loop causes the current in the circuit to oscillate at the frequency determined by the values of the inductor and capacitor.The active device acts as a negative resistance, which means that it has a negative voltage drop across it. This voltage drop causes the voltage across the inductor and capacitor to increase, resulting in an increasing oscillation frequency.The operating frequency of the EG-2102CA 156.2500M-LGPAL0 oscillator is set by adjusting the inductor and capacitor values. This can be done manually or electronically by using a voltage controlled oscillator (VCO) chip.The EG-2102CA 156.2500M-LGPAL0 oscillator is also designed with temperature compensation circuitry that keeps the oscillator output frequency stable over a wide temperature range. Temperature compensation allows the oscillator to maintain a stable output frequency even when the environment temperature changes. This is especially important for applications such as radar, where the environment can change drastically.

Conclusion

The EG-2102CA 156.2500M-LGPAL0 oscillator is a commonly used oscillator for telecommunications and other RF applications. It has a wide frequency range and a good response time. The working principle of the oscillator involves a negative resistance oscillator circuit with temperature compensation circuitry. This ensures that the oscillator remains stable over a wide range of temperatures.
