A Method to Calculate the Net Power Delivered into a TEM Cell Using a Directional Coupler in a Probe Calibration Application

Abstract:

In a probe calibration facility employing the TEM cell as the field generator, a method to calculate the net power delivered into the TEM cell is presented through monitoring the coupling power of the directional coupler. The new formula requires the effective reflection coefficient of the dual coupler and takes into consideration the directivity of the coupler, the mismatch between the coupler and the TEM cell, the mismatch between the power sensor and the coupling port of the coupler. The formula can provide sufficient accuracy in calibration purpose application using a TEM cell with a coupler combined with power sensors to monitor the net power.
