Abstract:
1. A system of detecting signal power comprising: a first interface port configured to receive a first-band signal and a second-band signal; a second interface port communicatively coupled to the first interface port and configured to receive a third-band signal, the second interface port communicatively coupled to the first interface port such that the first-band signal and the second-band signal propagate from the first interface port to the second interface port and such that the third-band signal propagates from the second interface port to the first interface port; and a common signal detector communicatively coupled between the first interface port and the second interface port such that the common signal detector is configured to receive the first-band signal, the second-band signal and the third-band signal and is configured to detect a first-band power level of the first-band signal, a second-band power level of the second-band signal, and a third-band power level of the third-band signal; and an attenuation unit communicatively coupled to the common signal detector and configured to substantially attenuate the first-band signal and the second-band signal before the first-band signal and the second-band signal are received by the common signal detector such that power detected by the common signal detector is associated with the third-band power level of the third-band signal.
