Excerpt from A Radio-Frequency Power Delivery System: Procedures for Error Analysis and Self-Calibration
An expression is developed for net power delivered to a load in terms of the indicated forward and reflected power and the system S-parameters and reflection coefficients. The dual directional coupler is treated as nonideal with power reflections assumed be tween all ports. The system itself is used to evaluate the major S-parameter terms in net power computation, and uncertainty in the computed power is derived from origins in the power meter readings and incompletely known S-parameters.
Key words: errors; error analysis; radio-frequency power; scat tering coefficients; S-parameters.
