US 12,756,606 B2 · Transceiver device and method thereof

Abstract

A transceiver device includes a conversion circuit, a phase-locked loop, a transmission processing circuit, a reception processing circuit, and a selection circuit. The conversion circuit performs a digital-to-analog conversion for a modulation data to generate a first control signal. The phase-locked loop includes a control circuit and a voltage-controlled oscillator. The control circuit generates a second control signal according to the modulation data, a reference signal, and a frequency signal. The voltage-controlled oscillator determines an oscillation frequency according to the first control signal and the second control signal to generate the frequency signal. The transmission processing circuit performs a transmission processing according to the frequency signal. The reception processing circuit performs a reception processing according to the frequency signal. The selection circuit selectively transmits the frequency signal to the transmission processing circuit or the reception processing circuit according to the modulation data.
