Features and benefits
Shielding performance
With the increasing coverage of the
electromagnetic spectra and the
constantly increasing use of electronic
hardware, the need for control on
electromagnetic interference is one of
the main issues in modern system
design. As a result, the Millipacs
connector system is anticipated with a
complete range of shielding
possibilities.
In order to evaluate the shielding
performance of the Millipacs
connector a measurement set-up was
designed based on a triaxial set-up
(figure 7), formed by an innerline (the
connector with his shield) and an
outerline (the shielding with an external
conductor). One of these transmission
line structures is used to forge a
current on the shield, the opposite is a
sense line to detect the induced fields.
Shielding effectiveness is a functional
method to characterize the shield
leakage, since it offers us the relation
between the measured power
progressing from shielding leakage and
the reference power delivered to the
test-cel.

effectiveness of the non-shielded

be noticed, the shielding effectiveness
is improved approx. 35 dB at higher
frequencies (3 GHz) when shielding is
introduced.
