ASTMHTE-100.000MHZ-AC-E application field and working principle

Oscillator is an electronic circuit that produces a continuous output signal with a specific frequency. It consists primarily of an active element with two ports, a bias element, a source, and a coupling element. The active element generates the desired signal, while the bias element controls the amplitude and frequency of the signal and establishes a steady-state operating point. The source supplies the power and the coupling element is used to transfer power between the circuit and the signal path.

Among various oscillator models, one of the common type is ASTMHTE-100.000MHZ-AC-E. This oscillator offers an optimal solution for applications requiring high frequency accuracy, excellent uniformity, ultra low jitter, low power consumption and fast start-up times. It operates at a center frequency of 100.000 MHz and has an output amplitude of +/ –2V peak-to-peak.

The working principle of the ASTMHTE-100.000MHZ-AC-E oscillator is based on the voltage-controlled oscillator (VCO) topology. The VCO generates an AC signal at its output, which is controlled by the voltage applied at its input. The frequency of the signal is determined by the applied voltage and is directly proportional to the voltage. The input voltage is usually generated by an external source, such as a temperature sensor or a signal generator.

The voltage-controlled oscillator consists of a transconductance amplifier, a resonant sub-circuit, an energy storage element, and an input voltage control loop. The transconductance amplifier integrates an AC signal into a DC voltage level, which is then fed back to the resonant sub-circuit to determine the resonance frequency. The output of the resonant sub-circuit is rectified and filtered to produce the desired AC output signal. This signal is then amplified and fed back to the voltage control loop. The input voltage control loop takes the input voltage and adjusts it to ensure that the output signal is within the acceptable range.

The ASTMHTE-100.000MHZ-AC-E oscillator is widely used in various applications, such as communications, instrumentation, and automation systems. It is also used in navigation systems for aircraft and ships, in radar systems for detection, and in digital circuits for timing control.

In conclusion, the ASTMHTE-100.000MHZ-AC-E oscillator is a highly efficient and reliable oscillator that provides excellent frequency accuracy and excellent uniformity. It is an optimal solution for applications that require high-frequency accuracy and low jitter. It is also low in power consumption and has fast start-up times.
