Our high-performance phase stable coaxial cables are engineered for demanding RF, microwave, and millimeter-wave (mmWave) applications where signal integrity, minimal phase change versus bending (Phase vs Flexure), and phase stability vs temperature are critical. Covering frequency ranges from DC up to 110 GHz, these cable assemblies offer low insertion loss, low VSWR, high shielding effectiveness (>90 dB), and extended flex life for field testing, radar systems, phased array antennas, and satellite communications.
Designed as direct drop-in equivalents for industry-standard series from Huber+Suhner, Gore, and Micro-Coax, we offer both standard lengths and custom RF cable assembly solutions built to your exact specifications.
Superior Phase Stability vs Flexure: Utilizes advanced microporous LD-PTFE and solid PTFE dielectrics to achieve minimal phase drift (±0.2° ~ ±0.3°/GHz) under repeated bending.
Phase Stability Over Temperature: Mitigates the “PTFE knee” effect, maintaining ultra-stable electrical performance across wide thermal ranges (-55°C to +125°C).
Ultra-Broadband Coverage: Precision assemblies supporting DC to 18 GHz, 40 GHz, 67 GHz, and up to 110 GHz with minimal attenuation.
High Shielding & Durability: Triple-shielded structures ensure >90 dB shielding effectiveness, wrapped in high-abrasion PUR, FEP, or armored jackets for harsh environments

A phase stable coaxial cable maintains a constant electrical length (and phase response) when subjected to physical bending, twisting, or temperature fluctuations. Standard cables suffer from phase drift due to dielectric deformation, which distorts phase-critical measurements in phased-array radars, vector network analyzers (VNAs), and beamforming systems.
Standard Solid PTFE dielectrics undergo a phase transition (known as the “PTFE knee”) near room temperature (~19°C), causing abrupt changes in phase length. Our high-frequency series (such as LD-PTFE models) use microporous PTFE dielectrics to mitigate this phenomenon, providing a near-linear phase change over a wide thermal operating range (-55°C to +125°C).
Yes. Our phase stable cable series are designed as direct, drop-in replacements for major industry brands including Huber+Suhner, Gore, and Micro-Coax, matching mechanical bend radii, connector interfaces, and RF performance specs.
A: For frequencies above 67 GHz up to 110 GHz, selecting cables with microporous LD-PTFE dielectrics and ultra-small outer diameters (such as 1.5mm to 1.8mm) is essential to minimize insertion loss and maintain strict phase stability under tight bend radii.
A: Yes. Our cable series match the electrical specifications, mechanical form factors, and connector interfaces (1.0mm, 1.85mm, 2.4mm, 2.92mm, SMA) of standard series like Huber+Suhner Minibend/SUCOFLEX and Gore CXN, providing a reliable, cost-effective drop-in alternative
