CE Series: Economical Semi-Rigid Coaxial Cable
For dense RF packaging where flexible cables fail, CE Series semi-rigid cables hold their exact formed shape—eliminating phase drift and spring-back. Low VSWR and Low PIM ensure clean multi-carrier signals, while 165 dB shielding blocks crosstalk in tight enclosures. Six models cover DC to 40 GHz, with cost-optimized CN variants for 18 GHz systems. Bend radii down to 1.27 mm and weights from 2 g/m suit production-volume RF instrument interconnects, phased-array modules, and airborne payloads.
Economical Semi-Rigid Construction
Solid seamless copper outer conductor provides inherent shape retention and superior shielding (165 dB). No need for expensive forming tools—CE Series is priced for volume production without sacrificing RF performance.
Low VSWR & Low PIM Performance
Uniform PTFE dielectric and precision-drawn center conductor (SCCS) ensure consistent impedance (50Ω) with low VSWR across the operating band. Low PIM characteristics support multi-carrier and sensitive receiver applications.
Wide Frequency Coverage
Six models span DC–40 GHz, with select CN variants optimized for 18 GHz systems. Velocity of propagation up to 77% minimizes phase delay, and voltage withstand ratings from 100 V to 500 V accommodate diverse power levels.
Tight Bend Radius for Dense Packaging
Static bend radii as low as 1.27 mm (CE020) enable routing in the tightest enclosures. Ultra-lightweight construction—starting at just 2 g/m—adds negligible mass to airborne and portable RF payloads.
Unreliable Phase Stability in Flexible Cables After Installation
Flexible cables shift phase when bent or vibrated. CE Series' solid copper outer conductor locks the geometry in place after forming, delivering repeatable phase and impedance performance that stays stable through environmental cycling.
High Cost of Custom Semi-Rigid Assemblies
Traditional precision semi-rigid cables carry a premium price tag. CE Series brings semi-rigid performance to cost-sensitive projects—ideal for production builds where every dollar of BOM cost matters.
PIM Degradation in Multi-Carrier Systems
Nonlinear junctions at connectors and cable interfaces generate passive intermodulation that degrades receiver sensitivity. CE Series' seamless copper outer and uniform construction minimize PIM sources for cleaner multi-carrier operation.
Space-Constrained RF Routing
When board-to-board or module-to-connector spacing is measured in millimeters, standard cable assemblies simply will not fit. CE020's 1.27 mm bend radius enables right-angle exits and serpentine routing inside the tightest RF modules.
RF Instrument Internal Interconnection
Precision-formed semi-rigid jumpers between modules within spectrum analyzers, network analyzers, and signal generators—where repeatable phase and low VSWR are critical to measurement accuracy.
Tight Space Cabling
Dense RF packaging in phased-array radar, satellite transponders, and military manpack radios—CE Series bends where flexible cables kink and holds shape without additional fixturing.
Wireless Infrastructure
Low PIM construction supports DAS, small-cell, and base-station jumper applications where passive intermodulation directly impacts network capacity and call quality.
Test & Measurement Fixtures
Repeatable semi-rigid connections for production test jigs and calibration standards—consistent electrical length ensures minimal measurement uncertainty across thousands of test cycles.
Aerospace & Defense
Wide temperature range (−55 to +150°C) and ultra-light weight options (2 g/m) make CE Series suitable for airborne, space, and portable military RF systems under strict SWaP constraints.
Medical RF Equipment
MRI coil interconnects, RF ablation generators, and diagnostic imaging modules benefit from CE Series' non-magnetic construction and consistent impedance in high-field environments.
