The AX7MBF1-173.3708C Oscillator is a positive-slope voltage-controlled oscillator (VCO) specifically designed for use in Communication Integrated Circuits (ICs). Developed by the semiconductor manufacturer Mitsubishi, the AX7MBF1-173.3708C is a versatile component capable of multiple operations in the application field of Communications ICs.

Applications

The AX7MBF1-173.3708C Oscillator is mainly used as a transceiver device in communication-related components such as mobile phones, modems, Wifi, Bluetooth and other mobile communication equipment. It is also used for the generation of carrier frequencies and low-noise bands for frequency-hopping spread spectrum systems. The VCO is designed for universal integration in a high-frequency range and is suitable for both analog and digital systems.

Working Principle

The main principle behind the function of this oscillator is the voltage-controlled frequency stability of the circuit. The circuit includes a tuned load that acts as a resonator, a varactor diode that acts as an electromechanical converter, and an amplifier that controls the frequency. The diode is biased and produces a voltage across the tuned load, which varies frequency in response to the applied voltage. The output voltage is a sinusoidal waveform, the frequency of which can be adjusted through the VCO control voltage.

The control voltage of the AX7MBF1-173.3708C Oscillator is output from the tuning circuit and connected to a bias resistor, which in turn produces the VCO output signal. The output signal is then fed back to the tuning circuit, which stores the voltage and adjusts the frequency of the output signal accordingly. This feedback control loop allows the oscillator to be tuned to a specific frequency and therefore increases its accuracy and stability.

Conclusion

The AX7MBF1-173.3708C Oscillator is a specialized component designed for use in Communication ICs. The component utilizes the voltage-controlled frequency stability principle to generate a carrier frequency and low-noise bands for frequency-hopping spread spectrum systems. The oscillator also has the ability to be tuned to specific frequencies for increased accuracy and stability. The AX7MBF1-173.3708C is a versatile component capable of multiple operations in the application field of Communications ICs.
