A frequency converter is a device used to generate an adjustable alternating voltage by using a constant-frequency voltage. A frequency converter converts a signal in one frequency range to a signal in another frequency range. A frequency converter generates a useful output frequency which is the sum or difference of the input frequency and the frequency of another signal, usually derived from a local oscillator. A typical frequency converter device uses a mixer to down-convert or up-convert an input signal to an output signal. The most typical application of frequency converters is controlling motors in such a manner that an adjustable voltage is generated from the alternating voltage of a supply network to control the motor. Controlling the speed or torque of a motor with a frequency converter permits a substantially lossfree adjustment of the motor to the requirements of the working unit driven by said motor. By using frequency converters, the rotation speed of a controlled motor can be increased considerably above the nominal frequency of the motor. Frequency converter circuits are widely used in the electronics field and especially in the RF field. They are used for converting an RF signal, transmitted over the air medium, to a lower frequency signal suitable for demodulation in a receiver. Frequency converters are typically implemented as analog multiplier circuits and are used in many different applications such as modulators, demodulators, upconverters, downconverters and mixers.
