Multi-Line RF Cable & Multi-Coax Cable Assembly for Automated Test Equipment

Multi-coax cable assembly (also called multi-line RF cable harness) integrates multiple RF coaxial lines and signal control lines into one single bundled assembly.

It is widely used in automated test equipment (ATE), semiconductor test benches, antenna test systems, radar, communication module verification and multi-channel RF measurement platforms.

Compared with separate single RF jumpers, multi-line RF harness greatly simplifies wiring inside the test cabinet. It reduces cable clutter, saves installation space, shortens wiring time and lowers the risk of misconnection during mass production testing.

Our Multi-Coax Cable Assembly Capabilities

✅ Mixed RF + low-speed signal integration: combine RF coaxial lines and digital signal wires in one harness

✅ Frequency range: DC to 8GHz / DC to 18GHz (custom higher frequency available)

✅ Connector options:

• 0.8/1.85mm, SMA, SMP, SSMA RF connectors
• D38999 military circular connectors
• HDC heavy-duty rectangular connectors
• D-SUB 25PIN signal connectors

✅ Cable types: B220, SS407 and other low-loss multi-coax cables

✅ Configurations: 4-port, 12-port, custom multi-port layout upon request

✅ Mechanical features: bundled shielding, strain relief, fixed housing, easy plug & play for test fixture

Typical Application Scenarios

1. Automated Test Equipment (ATE) Multi-channel RF test fixtures for RF front-end modules, filter, antenna and transceiver performance testing. One harness connects dozens of RF and signal channels at once.
2. Semiconductor Chip Test RF transceiver chips, Wi-Fi, Bluetooth, mmWave module wafer test and package test benches. Stable phase and low return loss guarantee consistent test repeatability.
3. Antenna Array & Radar Test Phased array antenna, multi-element antenna near-far field test system. Synchronized multi-line RF transmission keeps phase matching.
4. Defense & Aerospace RF Test D38999 sealed multi-coax harness for rugged, high-reliability test systems, suitable for outdoor and vibration environment.
