In one embodiment, a radio frequency (RF) power meter operates according to a
variable loop bandwidth according to the nature of the RF signal to be measured.
The RF power meter comprises: a first switch that switchably provides one of a
first signal and a second signal, wherein the first signal is the RF signal to
be measured; a first signal path for detecting an output signal from the first
switch and for providing a first comparison signal according to a first bandwidth,
a second signal path for detecting an output from the first switch and for providing
a second comparison signal according to a second bandwidth, and a second switch
that switchably provides one of the first comparison signal and the second comparison
signal to the first switch to complete a closed-loop for the RF power meter.
