Decoupled connectors provide the fast, better way to reduce noise and reduce ground loops on coaxial interconnections. The high frequency noise generated by fast rise times can cause both false triggering of circuits as well as emissions that can be radiated or conducted outside the equipment. Such emissions can interfere with nearby equipment. Ground loops are also a problem for networked systems. Ground loops are caused when two interconnected units are at different voltage potentials.
The typical way to handle such EMI and ground loop problems is to decouple the cable shield from the ground panel by soldering a ceramic disk capacitor between the cable shield and the panel. The capacitor shunts high-frequency noise to ground. While effective, this approach is time consuming and expensive.
The Capacitively Decoupled connector has built-in chip capacitors. These capacitors establish the electrical contact between the outer shield and a clip. This clip provides a short electrical path between the capacitors and panel. As a result, high-frequency noise is effectively shunted to ground, while the DC path is blocked.
The connectors offer compatibility in design and manufacture. The same footprint and dimensional envelope make them a drop-in replacement for standard BNC or TNC printed circuit board connectors. In addition, they can be robotically picked and placed for high speed automated assembly to PC boards.
