High inter-RX gain and phase mismatch drift over temperature
IWR2944ES1.0 ONLY
RX4 and RX3 exhibit +/-6 degree phase mismatch variation over the full allowed temperature range with respect to RX1 in IWR2944 in ES1.0 silicon.
In applications where high gain/phase accuracy is desired between RX channels, a background calibration can be used to correct for mismatch variation over temperature.
RX phase mismatch variation has improved to +/-4 degree in IWR2944 ES2.0 silicon across the full temperature range with respect to RX1.
