System and method for producing symmetrical modulated signals with arbitrary amplitudes - and phase control with the use of a modulation

摘要

Modulated difference - (symmetrical) signals are produced, wherein at least one of the signals in a phase relative to the other, can be controlled, and both of which could be controlled in an amplitude, and both of which have the same modulation envelope. In an exemplary embodiment, a coherent signal in a first electronic signal generator (esg) is generated and applied to a second esg. The coherent signal replaces the normal input signal of the second esg and the i - and the q - input signal of the second esg controlling the amplitude and phase of the output signal. This output signal is applied to a third esg, wherein the normal input signal to the vector modulator is replaced. The vector modulator is obtained by means of the same i - and q - input signal is controlled, as it is the first esg, as a result of which an output signal is generated, which has the same modulation envelope curve such as the output signal of the first has esg.
