Phase-Stable RF Cables, LISNs, and Microwave Interconnects

XGY Tek supplies precision RF test cables, network analyzer interconnects, and EMC pre-compliance accessories to laboratories worldwide. The catalogue spans DC to 110 GHz with phase- and amplitude-stable cable series, ruggedized armor options, and shielding effectiveness above 100 dB. For cable and LISN selection, see our RF test cable and accessory guide. Every cable ships with phase and insertion-loss characterization data and traceable calibration.

Which RF cable series should I use for VNA calibration vs. production test?
For VNA calibration and metrology benches, choose our VT series precision VNA test cables — engineered for repeatable calibration accuracy with <2° phase stability under flex. For production and field benches that get connected and disconnected frequently, the PT series precision test cables balance durability and performance. For high-vibration or moving environments — chamber rotators, AUT mounts, mobile racks — choose the GL series phase-stable cables with armored construction.
What is a Line Impedance Stabilization Network (LISN) and why do I need one?
A LISN provides a defined RF impedance between the DUT mains input and the AC supply, isolates external noise, and routes the conducted emissions to a measurement port for spectrum or EMI receiver capture. The EM5040 series is the compact LISN used in CISPR 16 and MIL-STD-461 conducted emissions pre-compliance benches. Pair with one of our spectrum analyzers for a complete bench.
Do XGY RF cables ship with characterization data?
Yes — every precision cable ships with insertion-loss, return-loss, and phase data measured against a calibrated reference, plus a traceable certificate of conformance. For high-end metrology applications we can also supply individually serialized cables with extended characterization across temperature. Discuss requirements via the quote form.
