ABSTRACT:
The present invention is directed to a power detection circuit for use in a wireless transmitting device. The circuit makes use of multiple gain paths so that two or more scaling factors are provided. Each scaling factor allows the detector circuit to provide more ADC levels per dB and thus provide accurate power control over a wider power range than through the use of a single gain path and a single scaling factor.
