Abstract

Some demonstrative embodiments include devices, systems and/or methods of estimating a phase between radio-frequency (RF) chains. For example, an apparatus may include a power detector coupled between first and second RF chains; and a phase estimator to estimate a phase difference between the first and second RF chains based on a combined power value detected by the power detector responsive to simultaneous communication via both the first and second RF chains.
