“…Several studies have contributed to the understanding and quantifying of electromagnetic interference due to PCB connectors. Some recent work was performed in [1] to analyze the radiation from a simplified PCB/connector structure based on network parameters. Reference [2] presented different skew compensation techniques for the same simplified PCB/connector structure to mitigate transmission line common-mode conversion.…”

“…In [1]- [2], the radiation physics were studied for a simplified PCB/connector structure which did not contain conductor or dielectric loss. Although the radiation physics for the simplified PCB/connector structure may be similar to the practical model from which it is based, research is needed to study the radiation physics for the practical, commercial model.…”

Electromagnetic radiation for a commercial printed circuit board (PCB) connector is investigated in this paper. The simulation models of the connector are shown to be validated by comparing measured and simulated S-parameters. Analytical formulas are provided to calculate the total loss and the radiated power from a PCB/connector structure when material losses are known. The total power loss for the considered geometry is shown to be dominated by material loss rather than radiated power loss. Termination schemes and additional geometry details in the connector model are also studied for their effects on the radiated power.

“…Among these works, radiation from the connector itself is not considered. In [5], radiation was predicted from S-parameters using the law of power conservation from a board with connector above 1 GHz. In [5], the investigated connector contained a single wafer including only two differential pairs.…”

“…In [5], radiation was predicted from S-parameters using the law of power conservation from a board with connector above 1 GHz. In [5], the investigated connector contained a single wafer including only two differential pairs. However, a full connector includes tens of wafers (typically 20 to 50+ wafers) with numerous differential pairs per wafer.…”

A technique to quickly predict the electromagnetic radiation for large connector array is proposed in the paper. Based on the S-parameters from a small section of a much larger connector, the S-parameters can be expanded to characterize a connector with any number of sections by only taking the nearest two sections into account. The proposed method shows good agreement with the radiated emissions from a full-wave solver. This technique is much faster than typical full wave solvers, and, often, the complicated full connector is too large of a problem for most computer simulations. Included in the work, it is shown that the predicted radiated power from connector increases proportionally with up to 45 sections/wafers.

In this paper we present a systematic method to evaluate radiation of multi-port integrated connector modules (ICM) by S-parameters. A novel test jig is designed and built to measure S-parameters of two columns of ICM ports simultaneously. Based on radiation physics of ICM, a radiation model is created and an F factor to correlate S-parameters to far field radiation is defined. A good correlation is found between the F value and radiation from ICM ports.
