Oscillators

An oscillator is an electrical circuit or component that produces a sustained oscillating voltage or current. Oscillators typically generate a periodic waveform such as a sine wave or a square wave. The ASTMHTD-20.000MHZ-AJ-E-T3 oscillator is an atomic oscillator operating at 20.000MHz, which is widely used in the military and aerospace industries. It is highly accurate, reliable, and able to operate for long periods of time without any degradation in performance.

Application Field

The ASTMHTD-20.000MHZ-AJ-E-T3 oscillator is mainly used in navigation, communication, and other defense-related applications. In the navigation application, the oscillator is used to accurately measure distance and location. This is accomplished by measuring the time delay for a signal to reach its destination. The clock is used as the timebase for this process, and the high accuracy of the ASTMHTD-20.000MHZ-AJ-E-T3 oscillator allows for pinpoint accuracy in the measurement.In the communication application, the high frequency and accuracy of the oscillator enables the transmission of data without the risk of interference. Since the data is transmitted with such precision and clarity, the accuracy and speed of communication systems relies heavily on the quality of their oscillators, and the ASTMHTD-20.000MHZ-AJ-E-T3 oscillator provides the highest quality available.In defense-related applications, the oscillator is used to precisely measure the frequency of high-power radio frequency (RF) signals. This enables the system to accurately identify and track enemy targets.

Working Principle

The ASTMHTD-20.000MHZ-AJ-E-T3 oscillator is based on an atomic clock, which is an electronic device that uses a continuously oscillating element to measure the exact length of a day. It is based on an atomic transition, which is the energy change between two different energy levels of an atom. The oscillator uses a single-crystal quartz resonator, which has a very small, constant frequency. This quartz resonator is connected to electrodes and immersed in a specially designed oven, which is controlled by an analog electrical circuit. When the power is applied, the resonator starts to oscillate at its pre-programmed frequency, and the voltage induced in the electrodes drive a frequency divider. This frequency divider divides the frequency by one kHz and sends the output signal to the user. The electrical circuit is designed to keep the frequency stable and reduce drift. The ASTMHTD-20.000MHZ-AJ-E-T3 oscillator is a highly accurate and reliable oscillator that offers unparalleled performance in applications such as navigation, communication, and defense-related applications. Its use of an atomic clock ensures accuracy and its quartz resonator ensures stability.
