With the introduction of HD signals the impedance of BNC con-
nectors becames more important than ever. Every deviate imped-
ance has a negative influence on the „return loss“ / „VSWR“
(Voltage Standing Wave Ratio) which are important measure-
ments for reflected signals in a transmission line. Especially on
high frequencies - as they occur when transmitting HD signals
(typical transmission @ 2.25 GHz) - an impedance mismatch
results in a lot of return loss.
Neutrik´s BNC connectors feature a true 75 7 design that meet
the stringent requirements of HDTV and sustain a consistent
impedance at high frequencies up to 3 GHz. To achieve this
result every Neutrik
®
BNC connector has been adapted to the
measurements of a small group of cables, this guarantees the
best possible performance and a little return loss.
The higher the frequencies the more pronounced is the „skin
effect“, which means that the energy moves to the outside of
the conductor. Therefore the plating of outer and center contact
is more important than on audio connectors with low frequen-
cies - both contacts of our BNC connectors are gold plated.

757BNC Connectors
Neutrik
®
offers a variety of 75 7 cable and chassis BNC connectors. The Push-Pull and RearTwist
®
cable connectors are easy to
handle in high density applications such as video patchbays and switches, provide a tactile and fast assembly and offer colour
coding as a standard. All parts of our BNC series are precisely machined to our high quality standards.
In times of rising frequencies the connector shielding becomes
to an important value in order to avoid EMI problems and
crosstalking. Neutrik BNC's take this fact into account and has
been equipped with an optimized ground contact design for
maximum shielding effectiveness.
Gold plated ground contact with improved shielding effectiveness
optimized for high frequency HDTV signal up to 3 GHz.
