Bundled RF Test Cables

Bundled RF Test Cables solutions help create flexible antenna patch cords for applications that require multiple runs, such as 5G. Spiral configurations of multiple flexible and ultra-flex jumper cables can be created under a common polyurethane outer jacket to facilitate installation and improve operation. The individual coaxial cables are spun together in an easily bendable fashion, essentially forming a bundle, and passed through a large jacket extruder where tear cords are placed.

                                               
This design can feed four or five individual RF Test Cables into the back of a single connector, such as RF Test Cables based on industry standard MQ4/MQ5 designs, including a four-contact connector and a five-contact connector . The most common structure of bundled RF Test cables is built with internal RF Test cables that are quarter inch or smaller and can be used for both non-low passive intermodulation (PIM) and low PIM interconnects. Constructions to address low PIM bundled harnesses include corrugated copper outer jackets and ultra-flexible flat braided construction.

                                             
Ensuring that the connectors are properly and securely tightened and eliminating any nonlinearity or poor electrical contact within the RF interconnect can also help reduce PIM issues. MQ4 and MQ5 cluster connectors use external spring contacts, so PIM performance does not depend on how well the tips of the external contacts mate. The connection between the male and female cluster connectors is sealed to IP67, as is the connector body and the transition from the cluster connector to the bundled cable. The solution is also keyed, eliminating the possibility of connecting the wrong RF Test cables to the wrong ports because RF Test cables can only be connected a certain way; no torque wrenches, know-how, or special techniques are required. The bundled RF Test cables solution detailed above looks better in terms of appearance, reduces significant labor costs, and provides a more robust solution with better UV and weather resistance. This helps support the densification needed to support the speed, coverage, high frequency and latency requirements of 5G.
