3.3 Calibration

A number of factors affect the calibration of the power detector such as frequency, power supply, slope & intercept of the transfer function, parasitic impedance presented by the transmission line and many more parameters. Please note that the calibration needs to be done for every implementation separately due to process variations as well. As this is outside the scope of this particular application note, please reach out to TI at E2E™ design support forum for assistance with a comprehensive design.
