Patent ID: 7925229

Claim:
A power detector, comprising: an initial-stage attenuator for attenuating a received signal, said initial-stage attenuator having a signal input and a signal output; a final-stage attenuator electrically connected to said initial-stage attenuator for also attenuating the received signal, said final-stage attenuator having a signal input and a signal output; at least one intermediate-stage attenuator connected in series between said initial-stage attenuator and said final-stage attenuator for also attenuating the received signal; an initial-stage detection unit connected to said signal input of said initial-stage attenuator for providing a first power measurement; an intermediate-stage detection unit connected to said signal output of said initial-stage attenuator for providing a second power measurement; at least one additional intermediate-stage detection unit connected to said signal input of said final-stage attenuator for providing a third power measurement; a final-stage detection unit connected to said signal output of said final-stage attenuator; and a determining module connected to each of said detection units for determining a power measurement of the received signal.
