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.

An apparatus comprising:
- a power detector coupled between first and second radio-frequency (RF) chains;
- and
- a phase estimator to estimate a phase difference between said 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.
A system comprising:
- a phased array antenna including a plurality of antenna elements connected to a respective plurality of Radio-Frequency (RF) chains;
- and
- a built-in-self-test architecture including:
- a plurality of power detectors coupled to a plurality of pairs of said RF chains;
- and
- a phase estimator to estimate a phase difference between first and second RF chains of a pair of RF chains based on a combined power value detected by a power detector of the plurality of power detectors coupled to said pair of first and second RF chains responsive to simultaneous communication via both the first and second RF chains.
A method comprising:
- simultaneously communicating a radio-frequency (RF) signal via first and second RF chains;
- and
- estimating a phase difference between said first and second RF chains based on a combined power value detected by a power detector, which is coupled between said first and second RF chains, responsive to the simultaneous communication via both the first and second RF chains.
A non-transitory product including a storage medium having stored thereon instructions that, when executed by a machine, result in:
- estimating a phase difference between first and second Radio-Frequency (RF) chains based on a combined power value detected by a power detector, which is coupled between said first and second RF chains, responsive to simultaneous communication of a RF signal via both the first and second RF chains.
