RBB calibration
RBB calibration is divided into two calibrations for low and high bands. Each calibration
consist of several smaller algorithms.
A3.3.1
RBB Low Band Calibration
Calibration steps:
1.
Save current configuration
2.
Start with calibrated value of the R.
3.
Approximate (by calculation) the control value of the RBANK.=>Register the value of
the RBB RBANKs control.
4.
Calibrate (by measurement using loopback path 7) the control value of the CBANK(
Low Band Section) at the 1.4MHz/2 bandwidth. => Register the CBANK control
value for the low-band section for 1.4MHz rxMode.
5.
Calibrate (by measurement using loopback path 7) the control value of the CBANK(
Low Band Section) at the 3MHz/2 bandwidth. => Register the CBANK control value
for the low-band section for 3MHz rxMode.
6.
Calibrate (by measurement using loopback path 7) the control value of the CBANK(
Low Band Section) at the 5MHz/2 bandwidth. => Register the CBANK control value
for the low-band section for 5MHz rxMode.
7.
Calibrate (by measurement using loopback path 7) the control value of the CBANK(
Low Band Section) at the 10MHz/2 bandwidth. => Register the CBANK control value
for the low-band section for 10MHz rxMode.
8.
Calibrate (by measurement using loopback path 7) the control value of the CBANK(
Low Band Section) at the 15MHz/2 bandwidth. => Register the CBANK control value
for the low-band section for 15MHz rxMode.
9.
Calibrate (by measurement using loopback path 7) the control value of the CBANK(
Low Band Section) at the 20MHz/2 bandwidth. => Register the CBANK control value
for the low-band section for 20MHz rxMode.
10.
Restore configuration
