ASTMHTFL-20.000MHZ-AR-E

Oscillators

The ASTMHTFL-20.000MHZ-AR-E is an example of an oscillator. An oscillator is an electronic circuit that produces a repeating signal without an input. It primarily consists of a power supply, an amplifier, and a resonator. In the case of the ASTMHTFL-20.000MHZ-AR-E, a quartz crystal is used as the resonator.

An oscillator is used to maintain a repetitive signal (oscillating waveform) of a certain frequency. It is used in a variety of applications, including generating precise signals used for testing and measuring electronic components, providing timekeeping, or generating signals used to create electricity from alternating current.

The ASTMHTFL-20.000MHZ-AR-E is a specific type of oscillator known as an “X-band”. X-band oscillators are designed for use at radio frequencies in the range of 8 GHz to 20 GHz. This type of oscillator is typically used in satellite applications, specifically for generating telemetry or for linking communication systems.

The working principle for the ASTMHTFL-20.000MHZ-AR-E is based on a classic feedback configuration. The power supply provides energy to be oscillated, and the quartz resonator provides an electrical signal that acts as a feed-back to the power supply. By properly adjusting the frequency of the power supply, an oscillating signal of 20.000MHZ is generated.

The feedback signal is generated by the resonator\'s equivalent impedance, which changes as a function of the incident frequency. When the incident frequency is close to the resonant frequency of the quartz crystal, the crystal resonates. This resonance causes a sharp impedance change, which in turn allows the amplifier to amplify the signal and this creates the feedback loop that produces the oscillator output.

As the name suggests, the ASTMHTFL-20.000MHZ-AR-E is designed for high frequency operation. To achieve this, the power supply needs to be able to provide a precise frequency and have low noise. It also needs to have low internal resistance for efficient energy conversion. To ensure stability, the amplifier that produces the oscillating signal must have a low gain, and the quartz crystal must be chosen carefully.

Overall, the ASTMHTFL-20.000MHZ-AR-E oscillator is an excellent example of a feedback oscillator. It is designed for use in radio frequencies in the range of 8GHz to 20GHz, making it suitable for applications such as satellite communication systems. Its detailed working principle is based on the classic feedback system, and it requires a low noise power supply, low gain amplifier, and precise quartz resonator.
