Classification: CPC H | IPC H

Claim 25:
26. The method of claim 24, wherein the determining of the calibration first phase setting comprises:
measuring, using the second transceiver module, a first signal power of a first dual-polarized RF signal including a first RF signal generated using the first transceiver module based on a first phase setting;
obtaining an offset first phase setting by adding a 180 degree offset to the first phase setting, and measuring, using the second transceiver module, a second signal power of an offset first dual-polarized RF signal including an offset first RF signal generated using the first transceiver module based on the offset first phase setting;
measuring, using the second transceiver module, a third signal power of a second dual-polarized RF signal including a second RF signal generated using the first transceiver module based on a second phase setting;
obtaining an offset second phase setting by adding a 180 degree offset to the second phase setting, and measuring, using the second transceiver module, a fourth signal power of an offset second dual-polarized RF signal including an offset second RF signal generated using the first transceiver module based on the offset second phase setting; and
based on a difference between the first signal power and the second signal power being larger than a difference between the third signal power and the fourth signal power, determining the first phase setting as the calibration first phase setting.
