Oscillators: ASTX-H11-16.000MHZ-I25-T

Oscillators are circuits that utilize a combination of resistors, capacitors, and active elements to generate a steady frequency for use in electronics and in other applications. The ASTX-H11-16.000MHZ-I25-T oscillator, developed by Astec, is a type of piezoelectric crystal oscillator with a wide tolerance range and a low power consumption. It is a simple voltage controlled oscillator that is extremely stable and is designed for applications such as short-wave communications and radar. This article will briefly explain its application field and working principle.

Application Field: The ASTX-H11-16.000MHZ-I25-T is designed to be used in long-range, shortwave communication systems. The low power consumption makes it suitable for use in battery-powered radio systems, while its excellent stability makes it well suited for use in digital cellular systems and radio navigation systems. It is also often used in satellite communications, consumer electronics, and robotics.

Working Principle: The ASTX-H11-16.000MHZ-I25-T is based on a resonant frequency produced by a piezoelectric crystal. The frequency of the voltage controlled oscillator is determined by the capacitance value of the crystal. The crystal is held in place between two electrodes and when a voltage is added to the circuit it causes the crystal to vibrate at a specific frequency, resulting in an output waveform. The output is then fed through a buffer amplifier which provides the voltage output.

In order to control the oscillator frequency, a voltage is applied to a resistor across the crystal to control the capacitance. This allows the user to adjust the frequency according to their needs. The amplitude stability of the voltage output is also adjustable, making the ASTX-H11-16.000MHZ-I25-T ideal for long-distance communication systems that require precision frequency control.

In addition, the ASTX-H11-16.000MHZ-I25-T operates in three modes: active, semi-active, and standby. In active mode, the oscillator constantly produces a frequency signal, making it well-suited for shortwave communications. In semi-active mode, the oscillator is powered up only when required, which is useful for battery-powered applications. Lastly, in standby mode, the oscillator is powered down and only wakes up when it receives a signal from the controlling device.

Overall, the ASTX-H11-16.000MHZ-I25-T is an extremely stable and reliable voltage controlled oscillator that offers great performance in a wide range of applications. Not only is it highly accurate and precise with its output frequency, but it also boasts low power consumption and long-term stability, making it a valuable solution for shortwave communication systems.
