Abstract
Some demonstrative embodiments include devices, systems and/or methods of detecting transmitter power. For example, a device may include a power detection circuit, coupled by a first coupler to a transmit chain, to provide a first output representing a measured non-calibrated transmission power over the transmit chain; a reference circuit, coupled to a reference voltage by a second coupler, to provide a second output representing a measured reference coupling factor; and a calibrator to determine a calibrated transmission power over the transmit chain based on the first and second outputs.
Claims29
A device comprising:
- a power detection circuit, coupled by a first coupler to a transmit chain, to provide a first output representing a measured non-calibrated transmission power over said transmit chain;
- a reference circuit, coupled to a reference voltage by a second coupler, to provide a second output representing a measured reference coupling factor;
- and
- a calibrator to determine a calibrated transmission power over said transmit chain based on the first and second outputs.
A system comprising:
- at least one wireless communication device comprising:
- at lest one transmit chain including a power amplifier connected to at least one antenna;
- at least one power detection circuit, coupled by at least one first coupler to said at least one transmit chain, to provide at least one first output representing a measured non-calibrated transmission power over said at least one transmit chain;
- a reference circuit, coupled to a reference voltage by a second coupler, to provide a second output representing a measured reference coupling factor;
- and
- a calibrator to determine a calibrated transmission power over said at least one transmit chain based on the first and second outputs.
A method comprising:
- determining a non-calibrated transmission power over a transmit chain, via a first coupler coupled to said transmit chain;
- measuring a reference coupling factor of a second coupler coupled to a reference voltage;
- and
- determining a calibrated transmission power over said transmit chain based on the non-calibrated transmission power and the reference coupling factor.
A non-transitory product including a storage medium having stored thereon instructions that, when executed by a machine, result in:
- determining a calibrated transmission power over a transmit chain based on a non-calibrated transmission power, which is detected over the transmit chain via a first coupler coupled to said transmit chain, and a reference coupling factor of a second coupler coupled to a reference voltage.
