Oscillators are widely used in communication systems, such as radio, television, telephone and so on. With the development of technology, various kinds of oscillators have been developed to suit different applications. The ASTMHTE-106.250MHZ-AC-E-T oscillator is one of them. It is mainly used for radio communication systems. This article will introduce the application field and working principle of this type of oscillator.

Application Field

The ASTMHTE-106.250MHZ-AC-E-T oscillator is a type of low-cost, low-power, high frequency oscillator with a frequency range of 105MHz-106.250MHz and a power output level of max. 5W. It is mainly used for radio communication systems and digital television broadcasting, especially suitable for navigation communication system.

The oscillator is mainly used for the signal modulation of 10KM-50KM transmission distance radio communication systems and helps the functions of adjusting frequency and transmitting signal. It is also suitable for digital television broadcasting system, as it is able to provide stable and direct broadcasts.

working principle

The ASTMHTE-106.250MHZ-AC-E-T oscillator has a closed loop structure in which the signal output from the antenna is amplified by the amplifier and the signal is filtered by the filter. The amplified signal is then fed back to the oscillator, which is consisted of an amplifier, a filter, a phase detector/charge pump, a voltage controlled oscillator (VCO) and a frequency divider/multiplier. The amplified signal is fed back to the VCO and the frequency of the signal is adjusted according to the input and output of the phase detector/charge pump.

The voltage from the VCO is then divided/multiplied in the frequency divider/multiplier and the divided/multiplied signals are amplified again by the amplifier. The amplified signals are filtered again by the filter to remove the unwanted noises and eventually the signal is output from the antenna.

The frequency of the output signal can be adjusted by controlling the amplitude and phase of the signal. Therefore, the ASTMHTE-106.250MHZ-AC-E-T oscillator can provide a stable and reliable output signal for radio communication systems and digital television broadcasting.

In conclusion, the ASTMHTE-106.250MHZ-AC-E-T oscillator is a type of low-cost, low-power, high frequency oscillator. Its application fields are mainly for radio communication systems and digital television broadcasting. It is also suitable for navigation communication system. The working principle of this oscillator is a closed loop structure which consists of an amplifier, a filter, a phase detector/charge pump, a voltage controlled oscillator (VCO) and a frequency divider/multiplier.
