Working Principle

The ASTMUPLPFL-500.000MHZ-LJ-E oscillator works on the principle of feedback and hysteresis. A small amount of electrical energy is input into the oscillator and this triggers an electrical current which then feeds back to the oscillator, creating a continuous loop. This loop, known as the resonant circuit, is the heart of the oscillator.

The resonant circuit contains a pair of capacitors and a pair of inductors. When these components interact, they create a current oscillation. The frequency of the oscillation is determined by the components’ ratios and geometric arrangements. This makes it possible to accurately control the frequency of the oscillator.

The oscillator also contains an amplifier circuit which amplifies the signal. This amplification increases the power of the signal, making it more suitable for communication networks. The output signal also has a lower phase noise, making it more suitable for navigation and positioning systems.

By manipulating the components in the resonant circuit, the frequency of the oscillator can be accurately controlled. This makes it possible to produce oscillators with very high frequency stability.
