DOCAT020V-040.0M Application Field and Working Principle

The DOCAT020V-040.0M is a voltage controlled oscillator developed by Doppler-Curie Company and is well known for its stability, low power consumption, and nonlinear performance. It has wide applications in frequency-shift keying (FSK), frequency modulation (FM), and other frequency-hopping modulation techniques.

The DOCAT020V-040.0M has two main parts, the die and the oscillator substrate. The die is composed of a substantially integrated circuit (IC) that contains an electronic mixer, frequency synthesizer, phase shifter, multiplexer, and other components. The substrate is composed of a polyester film, quartz crystal, and other materials.

In operation, the die is powered by an external source of DC voltage and the oscillator substrate receives the input waves. The input waves are then converted to a voltage signal that is of a frequency free to vary over a wide range. This voltage signal is then inputted into the electronic mixer to create a frequency-shift keying waveform, whose frequency varies with the number of inputs and their respective waveform. The basic waveform is then fed to the synthesizer, where it is multiplied or divided by a factor to increase or decrease the frequency. The synthesizer also can alter the phase shift of the waveform, thus allowing amplitudes or phases of multiple signals to change simultaneously.

The output from the synthesizer is then fed into the multiplexer, where it is selectively routed to different output terminals for further processing. In the DOCAT020V-040.0M, the output from the multiplexer is then fed to the power amplifier, which amplifies the signal strength before transmitting it. The power amplifier also improves the signal to noise ratio of the output waveform.

The DOCAT020V-040.0M is widely used for various applications because of its stability, low power consumption, and nonlinear performance. It is used in terrestrial transmitters, satellite applications, radio frequency identification (RFID) systems, and digital cameras, among other applications. Moreover, the DOCAT020V-040.0M has been found to be reliable for applications in the defense sector, since its signal transmission does not interfere with other airborne activities.
