5 Temperature Compensation

The AFE10004 features non-volatile memory (NVM) that can be programmed with the VGS compensation curve look-up table (LUT) for the application-specific PA. The device automatically enters a closed-loop operation, in which it monitors the operating temperature using local or remote temperature sensors and adjust VGS to maintain a constant power level. Each of the four output channels has independent LUTs, allowing for different FETs to be used in with a single AFE10004.
