Abstract:
1. A radio frequency (RF) power meter, comprising: a first switch that switchably provides an output signal from one of a first signal and a second signal, wherein said first signal is an RF signal to be measured; a first signal processing path for detecting said output signal from said first switch and for providing a first comparison signal according to a first bandwidth; a second signal processing path for detecting said output signal from said first switch and for providing a second comparison signal according to a second bandwidth; a second switch that switchably provides said second signal from one of said first comparison signal and said second comparison signal to said first switch to complete a closed-loop for said RF power meter; and an output block for providing information indicative of the power of said RF signal to be measured utilizing one of respective integrated signals generated by said first signal processing path and said second signal processing path.
