Device with steering and channel stitching for an extended bandwidth

A method of operating a radio frequency (RF) device, the method comprising:

• obtaining a first channel response associated with a received first signal at a first channel with a first frequency band;
• obtaining a second channel response associated with the received second signal at a second channel with a second frequency band,
• wherein the first frequency band and the second frequency band are different;
• calibrating the first channel response and the second channel response by steering to a calibration base;
• wherein calibrating the first channel response and second channel response includes:
• identifying a peak from one of a group consisting of the first channel response and the second channel response;
• defining a calibration base window based on the identified peak;
• and
• calibrating initial steering coefficients on the peak;
• and
• combining the first channel response with the second channel response for obtaining a combined channel response, wherein combining comprises channel stitching.

A radio frequency (RF) device, comprising:

• a first channel configured to receive a first signal in a first frequency band;
• a second channel configured to receive a second signal in a second frequency band that is different from the first frequency band;
• and
• control circuitry configured to:
• obtain a first channel response associated with the first channel using the received first signal;
• obtain a second channel response associated with the second channel using the received second signal;
• calibrate the first channel response and the second channel response by steering to a calibration base;
• and
• combine the first channel response and second channel response by channel stitching to obtain a combined channel response;
• wherein the control circuitry is further configured to:
• identify a strongest peak, in one selected from the group consisting of the first channel response and the second channel response;
• initially calibrate steering coefficients based on the identified strongest peak;
• define a calibration base window based on the identified strongest peak;
• and
• iteratively adjust steering coefficients over the calibration base window to identify a first peak.
