Abstract:
In some example implementations, there may be provided methods for beamforming calibration of active electronically steered arrays (AESA). In some implementations, one or more adders may generate a phase offset by adding phase calibration data from non-volatile memory and phase command data from static memory, and/or generate a gain offset by adding gain calibration data from the non-volatile memory and gain command data from the static memory. Further, a phase-shift circuit can modify, based on the phase offset, a phase of a first output signal, and an amplitude gain circuit can modify, based on the gain offset, an amplitude of the first output signal. In accordance with these implementations, the modified phase of the first output signal and the modified amplitude of the first output signal are provided to enable pre-calibration of the first output signal and/or a first antenna. Related systems, methods, and articles of manufacture are also described.

Claim (Index 34):
An apparatus comprising:\n a digital adder configured to generate a vector offset by at least adding vector calibration data obtained from non-volatile memory and vector command data obtained from static memory, the vector offset comprising a phase offset and/or a gain offset, the vector calibration data programmed into the non-volatile memory by at least burning of fuses, one-time programming, and/or electrically erasable programmable read-only memory; and a vector correction circuit configured to modify, based at least on the vector offset, a phase of an input signal and/or an amplitude of the input signal to provide an output signal, the modified phase and/or the modified amplitude provided to enable pre-calibration of the output signal, the vector calibration data programmed based at least on a measured difference in phase between a digital signal that is provided to an antenna and a radio signal that is output, based on the digital signal, by the antenna.
