The transmitter adopts DDS to generate local Larmor frequency for the region. A high-power switching circuit generates the high-power square wave,which resonates in the transmitter coil and the resonant capacitor to achieve high-power transmission.

• 该发射机采用DDS产生当地拉莫尔频率,通过大功率开关电路产生功率方波,由发射线圈和谐振电容产生谐振,实现大功率发射。
