Bundled, multiport cable assemblies for 5G network challenges
Times Microwave Systems has released its TMQ4 and TMQ5 bundled cable assemblies for 5G. These new solutions combine industry-standard four and five conductor MQ4 and MQ5 connectors with Times Microwave’s high-end coaxial cables. The assemblies offer a solution to the challenges associated with the increasing number of RF inputs required by the MIMO antennas commonly used to accomplish the densification needs of 5G networks.
The TMQ4 and TMQ5 bundled coaxial cable solution design helps reduce the number of individual connections hooked up while creating a more rugged solution, according to the company. Harnesses are available with weather protection boots to seal them to IP-67 specification and they also feature UV resistance, adding to the assembly’s durability for long-term performance.
Available with Times Microwave’s LMR cables and low PIM options such as the SPO and TFT-5G, these bundled solutions are 0.25 in and smaller. They are also available in several other constructions, including corrugated copper outer sheaths and ultra-flexible flat braid constructions.
Extruded polyethylene fillers create a round cable for optimal weather sealing and clamping, finished with one of several jacket material options for the most demanding applications. The TMQ4 and TMQ5 cluster connectors are also keyed with a colour code on the outer coupling nut to make engagement quick and easy. In addition to the male-to-male bundled harness, the female bulkhead connector is also available as a finished assembly ready to be installed into the box and engaged with the PCB.
The increasing demand for high coverage MIMO antennas used in 5G applications has led to substantial growth in RF ports. Furthermore, says Times Microwave, 5G antennas are shrinking as higher frequency bands need to accommodate larger bandwidth requirements, translating into more antennas in a smaller space. This densification creates numerous challenges related to installation, torquing, ensuring proper weather sealing.
“Times has a long history of building quality cables and connectors, along with the expertise, processes, techniques, and materials to create custom solutions that solve the specific needs of our customers, and the new TMQ4 and TMQ5 solution is a strong example of that innovation,” said Kevin Moyher, product manager at Times Microwave.
