Abstract
A calibration unit for calibrating a single cable interface operably coupling an SDU to an antenna includes a calibration loopback path operably coupled to a first path of the antenna and a second path of the antenna, a first path switch and a second path switch operably coupled to the first and second paths of the antenna, respectively, to alternately connect and disconnect the first and second paths of the antenna to the calibration loopback path where the first and second paths of the antenna are operably coupled to a first end of the single cable interface, a first detector operably coupled to a second path of the SDU among a first path of the SDU and the second path of the SDU that are each operably coupled to a second end of the single cable interface, the first detector being configured to detect a first signal at the second path of the SDU, an SDU DSP operably coupled to the first detector, a second detector operably coupled to the first path of the antenna to detect a second signal at the first path of the antenna, and an antenna DSP operably coupled to the second detector. The antenna DSP determines a first gain adjustment based on a test signal inserted at the first path of the SDU and the first signal and the second signal, and the SDU DSP determines a second gain adjustment based on the test signal, the first signal and the second signal.
