Abstract
A converting/steering device has a normal mode and a calibration mode. The converting/steering device includes a merged mixer/VGA and a mode controller. The merged mixer/VGA has a mixing stage and an amplifying stage. In the normal mode, the mode controller deactivates the mixing stage of the merged mixer/VGA, and the device operates as an RF VGA. In the calibration mode, the mode controller activates the mixing stage of the merged mixer/VGA and passes a local oscillator signal to the mixing stage, so that the device operates as a down-mixer.
