Oscillators provide the alternating current necessary for many electronic applications. ASTMHTE-48.000MHZ-AJ-E-T is a type of oscillator mainly used in digital frequency control systems. This type of oscillator can accurately generate high-frequency harmonics with its advanced structure and unique direction-control examination system. In this article, we will thoroughly explore the application field and working principle of ASTMHTE-48.000MHZ-AJ-E-T oscillators.

The application field of ASTMHTE-48.000MHZ-AJ-E-T oscillators includes the radio communication system, digital signal processors and frequency control systems. In the radio communication system, they are used to generate precise sinusoidal signal sources at the desired frequencies. These signals can be amplified and transmitted to different receivers. In digital signal processors, they are used to control the frequency of the sampling pulse. The frequency accuracy of these oscillators ensures the efficient operation of the digital system. Frequency control systems, such as digital alarm clocks, require the accurate oscillation period from the oscillator. ASTMHTE-48.000MHZ-AJ-E-T oscillators can meet such needs.

The working principle of ASTMHTE-48.000MHZ-AJ-E-T oscillators is based on the negative feedback mechanism. A voltage-controlled oscillator (VCO) is employed in the oscillator which generates a frequency- modulated output signal. The output signal is then fed back to the input of the oscillator through a feedback network. This feedback network consists of an amplifier, filter and a phase shifter. The amplifier ensures that the feedback signal stays in phase with the input signal, while the filter strips off any high-frequency components that might distort the signal. The phase shifter ensures that the feedback signal leads slightly in phase with the input signal, thereby forming a positive feedback loop. This positive feedback loop is what makes the oscillator oscillate.

In order to keep the frequency and amplitude of the oscillator stable, the oscillator has to be equipped with a frequency control system. This control system consists of a frequency-detection circuit and a frequency-control circuit. The frequency-detection circuit extracts the frequency information from the output signal of the oscillator and sends it to the frequency-control circuit. The frequency-control circuit then applies a corrective voltage to the VCO in order to keep the frequency of the oscillator constant. This keeps the frequency of the oscillator stable and within the desired tolerance.

To summarize, ASTMHTE-48.000MHZ-AJ-E-T oscillators are widely used in digital frequency control systems due to its advanced structure and unique direction-control examination system. These oscillators are based on a negative feedback mechanism and employs a frequency control system in order to keep the frequency and amplitude of the oscillator stable. Therefore, it provides an accurate oscillation period at the desired frequencies and makes them ideal for radios, digital signal processors and frequency control systems.
