Abstract
A compensated signal source (210, 220) utilizes baseband signals and a radio frequency carrier signal to generate a set of source output signals (226, 227) which are coupled to a particular circuit (230, 240, 250). The signal source (210, 220) is operable in a characterizing mode in which a test configuration is applied, and outputs from the signal source and the particular circuit measured to develop parameters representing imperfections within the signal source and within the particular circuit. The signal source (210, 220) is operable in a normal mode, in which compensation based on the measured parameters is applied to account for the imperfections. In a preferred embodiment, the particular circuit (230, 240, 250) and compensated signal source (210, 220) form part of an amplifier (200) that implements linear amplification using nonlinear components (LINC) techniques.
