频率切换器、RFID系统以及集成该频率切换器的距离测量设备
摘要：
本发明涉及频率切换器、RFID系统以及集成该频率切换器的距离测量设备。调制器可以利用包括用作I信号和Q信号的Sin信号和Cos信号的正交信号，调制载波。频率控制器可以控制该正交信号的频率，以切换该载波的发射频率。发射机可以利用该切换发射频率，发射该调制载波。
摘要（英）：

A modulator is operable to modulate a carrier wave with quadrature signals including a Sin signal and a Cos signal which serve as an I signal and a Q signal. A frequency controller is operable to control frequencies of the quadrature signals to switch a transmission frequency of the carrier wave. A transmitter is operable to transmit the modulated carrier wave with the switched transmission frequency.
