Abstract
A calibration signal is transmitted from a transmitter antenna. A receiver antenna receives a loopback signal that results from an air coupling of the receiver antenna and the transmitter antenna. The loopback signal is compared to a target. If the loopback signal does not meet the target, then a gain of the calibration signal is adjusted and the loopback signal is again checked against the target. When the loopback signal meets the target, the gain is taken as a calibrated transmitter gain.
