Method, and the RF transmitter circuit in order to modulate the output voltage of the RF transmitter circuit

摘要

Topic Standard of application of the supposition object is satisfied, at the same time, offer with the method and the RF transmitter circuit in order power consumption is lower than every method for this object, and each of the circuit to modulate the output voltage of the RF transmitter circuit.SolutionsThis invention being method in order to modulate the output voltage of the transmitter circuit which possesses with the voltaged controlled oscillator and the digital/analog converter and the antenna circuit, transmits the output signal of sufficient power from the voltaged controlled oscillator to the antenna circuit directly, at the same time, regards the method of modulating the frequency of the output signal of the voltaged controlled oscillator directly. This invention, furthermore, being the transmitter circuit which possesses with the voltaged controlled oscillator and the digital/analog converter and the antenna circuit which possess the tank circuit, in order the voltaged controlled oscillator, the output signal of sufficient power to transmit to the antenna circuit directly, having conformed and being converted, at the same time, in order the digital/analog converter, to modulate the output frequency of the voltaged controlled oscillator, it regards also the transmitter circuit which is formed. In order to make the frequency of the voltaged controlled oscillator modulate, can the capacitive load circuit, connect to the tank circuit or the quartz oscillator circuit of the voltaged controlled oscillator.
