PCB mounting meets bandwidth
requirements
Cambridge Connectors' new PCB edge mounting style provides a straight signal path along the connector, through the point of interface and onto the PCB track.
High-definition TV applications are pushing the operating parameters of interconnection products in the broadcast industry to the limit The design and use of BNC connectors (the industry's connector of choice) has had to adapt to keep up with the ever increasing demand for greater bandwidth

BNC connector comes in two parts
Removing boards from broadcast mixers, switches or routers, when in service, is usually a time consuming and costly operation because all the related cables first have to be disconnected.
Ethernet connectors take magnetics onboard
RJ45 connectors with integrated magnetics offer several benefits in terms of electrical performance, equipment size and overall costs.
The challenge lies not only in the basic design of this connector range (BNC connectors were originally designed for 50ohm applications) but also on the way in which the connector is terminated.
The PCB layout and the connector-to-board interface, therefore, are as important as the intrinsic properties of the connector.
With this in mind, when re-engineering its new true 75ohm BNC connector, which is fully RoHS compliant, Cambridge Connectors also incorporated an innovative PCB edge mounting style.
This provides a straight signal path along the connector, through the point of interface and onto the PCB track with minimal loss of transmission characteristics.
The resultant VSWR of 1.09(Max) over a frequency range of 0 - 1.5GHz and working voltage of 500V rms means this BNC connector more than meets HD Serial Digital Video requirements.
An additional benefit of the card edge style is the lower profile, enabling higher wiring densities, which is a major consideration in the design of broadcast equipment.
To complement this new product Cambridge Connectors also produces True 75ohm BNC patch leads in either standard length or built to customer specifications.
A 75ohm optimised PCB layout guide is available on request.
