Abstract
A transmit power measurement apparatus includes a transmit power detection path, a compensation circuit and a tracking circuit. The compensation circuit includes a programmable filter device and a compensation controller. The programmable filter device generates a filter output. The compensation controller sets the programmable filter device at least based on a frequency response of the transmit power detection path. The tracking circuit generates a transmit power tracking result at least based on the filter output.
