    • A non-contact motion detection apparatus includes at least one reception antenna, at least one transmission antenna, a voltage-controlled oscillator (VCO) and a phase lock loop (PLL). The at least one reception antenna receives a first wireless radio frequency (RF) signal. The at least one transmission antenna transmits a second wireless RF signal to an object which reflects the second wireless RF signal into the first wireless RF signal. The VCO outputs an oscillation signal to the at least one transmission antenna. The first wireless RF signal received by the at least one reception antenna is injected to the VCO. The PLL generates a control voltage to the VCO according to the oscillation signal from the VCO and a reference frequency. Controlled by the control voltage, which represents a motion information of the object, the oscillation signal of the VCO is locked to the reference frequency.

    • The microwave transmitter of the present invention can perform two-terminal dynamic modulation with respect to the voltage supply terminal and the RF input terminal of a RF power amplifier. The microwave transmitter of the present invention comprises a first modulator and a second modulator. The first modulator uses the baseband digital delta-sigma modulation technique to process the envelope signal and outputs this signal to the voltage supply terminal of the RF power amplifier as a supply voltage. The second modulator uses the baseband digital pre-distortion technique to process the IQ-modulated carrier and outputs this signal to the RF input terminal of the RF power amplifier as a RF input signal. Thereby, the RF power amplifier can highly efficiently reconstruct the power-amplified RF modulated carrier without distortion at the RF output terminal. In addition, the baseband digital processing techniques used in the two modulators make the microwave transmitter of the present invention suitable for multi-mode operation.
    • 本发明的微波发射器可以相对于RF功率放大器的电压供给端子和RF输入端子进行两端动态调制。 本发明的微波发射机包括第一调制器和第二调制器。 第一调制器使用基带数字Δ-Σ调制技术处理包络信号,并将该信号作为电源电压输出到RF功率放大器的电压端。 第二调制器使用基带数字预失真技术来处理IQ调制的载波,并将该信号作为RF输入信号输出到RF功率放大器的RF输入端。 因此,RF功率放大器可以在RF输出端子处高效地重构功率放大的RF调制载波而不失真。 此外,在两个调制器中使用的基带数字处理技术使得本发明的微波发射器适合于多模式操作。
