In this work, a modified low pass filter with 20 dB improved rejection at the center frequency of the RF injection network was developed to monitor the RF rectification of an active implantable medical devices (AIMD) during conductive emission testing. Transfer function of the designed filter was calculated, verified and validated by ADS simulation and S-parameter measurement using RF network analyzer. Analytical calculation, simulation and measurement results of the filter transfer function are in good agreement.
