技術摘要: |
一種差動射頻訊號傳送機,包括振盪器、調變器與放大器模組。振盪器用以產生一對差動振盪信號。調變器根據一輸入信號與該對差動振盪信號產生一對差動調變信號,其中該輸入信號為一數位信號,當輸入信號為一第一狀態時,該對差動調變信號為該對差動振盪信號,並且當輸入信號為一第二狀態時,該對差動調變信號為一定電壓訊號。放大器模組接收並放大該對差動調變訊號,以產生一對差動射頻信號。
A differential radio frequency signal transmitter is provided. The differential radio frequency signal transmitter includes an oscillator, a modulator and an amplifier module. The oscillator generates a pair of differential oscillation signals. The modulator generates a pair of differential modulated signals according to an input signal and the pair of differential oscillation signals. The input signal is a digital signal. When the input signal is at a first state, the modulator outputs the pair of differential oscillation signals as the pair of differential modulated signals, and when the input signal is at a second state, the modulator outputs a constant voltage signal as the pair of differential modulated signals. The amplifier module receives and amplifies the pair of differential modulated signals and generates a pair of differential radio frequency signals, accordingly.
