Abstract
A radio frequency (RF) power source having a precise power detector includes a RF signal generator, a RF power amplifying circuit, a power supply circuit, and a precise power detector. The precise power detector includes a voltage mutual inductor, a current mutual inductor, a precise detecting module, and a microcontroller integrated with an analog-digital (A/D) converter and a micro-processing unit, wherein the voltage mutual inductor and the current mutual inductor are respectively connected with the precise detecting module. The precise detecting module includes an add circuit, a subtraction circuit, a rectification circuit, and a filtering-amplifying circuit, wherein the add circuit and the subtraction circuit are respectively connected with the rectification circuit, the rectification circuit connects to the filtering-amplifying circuit, the filtering-amplifying circuit connects to the microcontroller integrated with the A/D converter and the micro-processing unit.
