Abstract
"Shunt capacitive filtering is usually ineffective at high frequencies because of mutual inductance between the filter input and output loops. Standard two-terminal, surface mounted ceramic chip capacitors were compared with recently introduced three-terminal capacitors and direct shorts, over the frequency range of 300 kHz to 6 GHz. Above the series resonance frequency, the three-terminal capacitor provided at least 15 dB more attenuation than the same value of two-terminal capacitor, for 50 Ω source and load resistances. The three-terminal mounting configuration results in significantly less mutual inductance between the loop intended to carry the noise current and the loop intended to carry only the signal current. The mutual inductance of the capacitor-mounting configuration is the key parameter that determines the high-frequency attenuation of shunt mounted capacitive filters. An equivalent circuit model was developed that predicts the shunt capacitor filter performance using a simple analytical estimate of the mutual inductance"--Abstract, page iii.
