Industry Platform
Low-loss RF, fiber and Ethernet cable assemblies engineered for 5G base stations, network infrastructure, antenna feeders and PoE equipment — impedance-controlled to 6 GHz+, SMA / N-type / FAKRA terminated and IP67-sealed for outdoor service.
Application Context
A telecom cable assembly is judged on signal integrity, not just continuity. RF feeder and jumper runs have to hold impedance, keep insertion loss low and control PIM, while Ethernet and high-speed data runs have to reject EMI and crosstalk over distance. On top of that, most of this hardware lives outdoors — on a rooftop, up a tower or in a curbside enclosure — so the same harness needs UV-stable jackets and IP67 sealing to survive a -40°C to +85°C environment for years. That combination of electrical and environmental demand is why telecom harnesses use low-loss coax, validated RF connectors and tested terminations rather than general-purpose wire.
Across a network the wiring changes job at every layer: low-loss RF jumpers where the 5G radio meets the antenna, LMR-style and semi-rigid feeders on the tower, micro-coax for multi-gigabit fronthaul and board-to-board links, shielded twisted-pair and RJ45 / M12-D Ethernet inside switching and edge nodes, and PoE harnesses out to customer-premise equipment. We build all of these as custom, pre-terminated, in-house-tested assemblies. For RF feeder and jumper paths we draw on our coaxial cable assembly service; for tight, high-speed links our micro-coaxial cable assembly line; and where automotive-telematics interfaces appear, our FAKRA cable assembly service.
Applications
Low-loss RF, fiber and Ethernet assemblies for every layer of the network.
Low-loss RF jumpers and DC power harnesses for macro base stations, small cells and massive-MIMO radios. Phase-stable coax and weatherproof terminations keep insertion loss and PIM down where the radio meets the antenna.
High-density harnesses for switching centers, core routers and edge-compute nodes — power, ground, RJ45 / M12-D Ethernet and intra-rack signal looms bundled and labeled for fast install and clean airflow.
Antenna feeder and inter-radio jumper assemblies built with LMR-style and semi-rigid coax. Controlled impedance and shielded construction protect signal integrity on rooftop, tower-mount and outdoor enclosure runs.
Micro-coax and fiber assemblies for fronthaul, backhaul and high-speed board-to-board links. Tight-tolerance micro-coax handles multi-gigabit data where space and bend radius are at a premium.
Cable assemblies for ONTs, gateways, access points and PoE-powered devices — Ethernet, power and antenna leads combined into clean, install-ready harnesses for indoor and outdoor CPE.
Engineering Challenges
Impedance control, low insertion loss and controlled PIM on RF feeder and jumper runs, verified so the harness does not become the weak link between radio and antenna.
UV-stabilized jackets, corrosion-resistant connectors and IP67 sealing rated -40°C to +85°C for rooftop, tower-mount and outdoor-enclosure exposure.
Factory-terminated SMA, N-type, FAKRA and RJ45 / M12-D contacts — crimped, torqued and tested in-house so no terminations are made in the field.
Each RF assembly is verified for impedance and loss, with foil-plus-braid or double-braid shielding to limit leakage and crosstalk on antenna-feeder and jumper runs.
Technical Capabilities
ISO 9001 manufacturing built to IPC/WHMA-A-620 workmanship, with impedance-controlled RF processing, fiber termination and IP67 outdoor assembly under one roof.
Manufacturing Process
Quality & Testing
Every telecom harness gets continuity and impedance/RF verification, with torque-controlled, tested terminations and shielding checks where the application calls for it — all documented for lot-level traceability before it ships.
Why WHP
RF-engineered cable assemblies built for 5G and next-generation network infrastructure.
Assemblies are built for low insertion loss, high return loss and controlled PIM. We hold 50 Ω (and 75 Ω) impedance and verify it, so the harness does not become the weak link between radio and antenna.
UV-stabilized jackets, corrosion-resistant connectors and IP67 sealing withstand years of rooftop, tower-mount and outdoor-enclosure exposure across a -40°C to +85°C temperature range.
From LMR-style RF coax and micro-coax to shielded twisted pair and PoE Ethernet, mixed-signal telecom looms are built and tested as one assembly instead of being split across vendors.
Harnesses are manufactured to IPC/WHMA-A-620 Class 2/3 workmanship under our ISO 9001 quality system, to RoHS material requirements and your telecom EMC targets.
Our telecom harnesses are made to IPC/WHMA-A-620 workmanship under our ISO 9001 quality system, built to RoHS material and telecom EMC requirements for signal integrity and outdoor durability.
