Abstract

The present invention is directed to a vector monitor for use with a transmitter employing in-phase and quadrature phase input and feedback signals, and a method of controlling a transmitter. In one embodiment, the vector monitor includes an error detection circuit configured to provide first and second components of an error signal based on the input and feedback signals. Additionally, the vector monitor includes a comparator circuit, coupled to the error detection circuit, configured to compare a resultant vector of the first and second components to a comparison boundary and control a power level of the transmitter based on the comparison.
