| 摘要 |
This invention relates to an RF transmission-reception device comprising: an antenna (11), a transmission part (12) that includes a power amplifier (17) that outputs an RF signal with modulated power to the antenna (11), a reception part (13'), a digital processing and interface module (14), in which the input signal is picked up at the reception part (13') by taking a current sample at the power supply regulator (16) to generate an image current of the current amplitude output by the antenna (11) to the power amplifier (17).
