Patent ID: 8193859

Claim:
A detection circuit comprising: a first detector circuit adapted to receive a sample of output power from a power amplifier (PA) of a transmitter and generate a first signal having a magnitude that is proportional to low to medium levels of output power of the PA; a second detector circuit adapted to receive the sample of output power from the PA and generate a second signal having a magnitude that is proportional to medium to high levels of output power of the PA; and a control circuit adapted to control a continuous transition between urging a predominance of a contribution to a detector output voltage from the first signal to the second signal as the output power of the PA transitions from low to medium levels to medium to high levels, and to control a continuous transition between urging the predominance of the contribution to the detector output voltage from the second signal to the first signal as the output power of the PA transitions from high to medium levels to medium to low levels.
