Oscillators

An oscillator is an electronic circuit that produces a periodic or repetitive signal, usually a sinusoidal waveform. Oscillators are widely used in many electronic applications, such as communication systems, clocks, radio receivers, sound production, and so on.

The 550MD194M400DG oscillator is a frequency synthesizer that uses direct digital synthesis (DDS) technology. It is a phase-locked loop (PLL) oscillator that allows for variable frequency output over a wide range of frequencies. It has a typical frequency range of 3.440GHz to 3.520GHz, and a typical output power of +17 dBm. The oscillator can be configured for different output frequencies and then locked onto the desired frequency with a direct digital synthesizer. It is designed for low-phase noise, low consumption, and stability. It is capable of providing stable frequency synthesis with a low-jitter signal.

The 550MD194M400DG oscillator is used in a variety of applications, such as broadcast and communication system, radar system, local oscillator, satellite receiver, test equipment, and many more. This oscillator is suitable for a range of frequencies from 100 kHz to 3.5 GHz, with a typical output frequency of 70 MHz to 4.8 GHz. It is designed to be programmable with a frequency resolution of 15 MHz to 10 kHz.

The working principle of this oscillator is based on the PLL principle. The PLL is used for frequency synthesis in the oscillator, which requires a low phase noise oscillator and a voltage controlled oscillator (VCO). The PLL circuit is composed of loop filter components, such as resistor, capacitor, and frequency divider. The frequency dividers are used to divide the output of the VCO to a lower frequency and feed it back to the PLL. Through this process, the PLL can achieve a stable frequency to output from the oscillator.

The 550MD194M400DG oscillator is an integrated PLL synthesizer module and is a highly integrated device for signal generation. It can be programmed to generate a wide range of frequencies and maintain phase lock across the temperature range of 0°C to 70°C. The oscillator is designed for low jitter performance, low power consumption and high linearity over the full frequency range of 3.440GHz to 3.520GHz.

In conclusion, the 550MD194M400DG oscillator is a highly integrated PLL synthesizer used in many applications, such as communication systems, broadcast systems, satellite receivers, and more. It features low phase noise, low jitter, low power consumption, and wide frequency range, which makes it suitable for a variety of applications.
