Prevent PIM within your connector and cable by doing the following: 1. Design out loose interfaces. Consider fully soldered connections. 2. Avoid use of any ferrous materials in the connector. Don’t use nickel in any platings. 3. Ensure that there are no stray metal flakes or oxidized metals within the cable or connector insulators. 4. During final assembly, ensure that the connector-to-cable or connector-to-board interface is tight. Once impedance is under control, insertion loss at a minimum, and PIM has been addressed in your designs, you still must consider crosstalk internal to the connector. To reduce crosstalk issues, shielding can be introduced between contacts if there is room. In addition, when working with a board connector, the main cause of impedance and crosstalk issues exists where the connector attaches to the board. When working on the cable connector, watch how the conductors of your cable mate to the contacts within the connector. Spacing must be controlled, and the method of termination — either crimp, solder, or insulation displacement — must be consistent. When working with a multi coax cable, in addition to dealing with the signal
HTP-High-speed Twisted Pair Multi-Gigabit Ethernet Connector Series from IMS features data transmission rates to 20 Gb/s; compact and modular design; and single, double, or quad versions. They can be watertight (upon request) and are designed for twisted pair cabling.
MCA-Mini Coax highspeed automotive connector from IMS features data transmission rates to 20 Gb/s, RF performance to 15 GHz, and single to 4 coax versions. It is significantly smaller than FAKRA series connectors. Through hole and SMT versions are available.
