Cable Series Overview
HPI/LAI Series
The HPI/LAI Series offers highly configurable cable assemblies with options for phase matching and custom marking. Available with high-performance HP and low-attenuation LA cable series, these assemblies feature a wide selection of interfaces and cable jackets. Connectors are designed to meet MIL-C-39012 standards for optimal performance and cable transition. Suitable for applications up to 50GHz.
HPT Series
The HPT Series is ideal for lab and production testing and high flexure applications up to 50GHz. Featuring a heavy-duty, hot-molded rubber boot for exceptional strain relief and extended lifespan, these assemblies are designed for excellent connector adhesion and meet MIL-C-39012 standards.
DKF Series
The DKF Series is designed for lab and production applications up to 18GHz. It features a heavy-duty slip-on rubber boot for strain relief and connector adhesion, meeting MIL-C-39012 standards. Standard lengths with straight male connectors are available.
SWI Series
The SWI Series offers a higher performance alternative to RG series cable assemblies, ideal for in-box or in-cabinet applications up to 18GHz. These assemblies meet MIL-C-39012 standards and are designed for simplified connector attachments.
HP Series
With a long history in military and aerospace, the HP Series is a preferred interconnect cable for ground, sea, and airborne systems, as well as test and measurement applications. Offering high performance, flexibility, and a wide range of connectors for applications up to 50GHz, these cables feature triple shield construction for robust connector attachments and resistance to harsh handling.
LA Series
The LA Series provides the best combination of low attenuation, phase stability, and mechanical performance, with signal loss at 18GHz for LA290S being <20 dB/100 ft and for LA190S <37 dB/100 ft. Engineered for excellent bend and crush resistance, and phase stability over temperature and flexure.
KW Series
The KW Series offers ultra-low attenuation comparable to rigid, corrugated cables, with higher power ratings and excellent flexibility. Featuring copper clad aluminum center conductors and a pliable polyurethane jacket, these cables are suitable for tight installations and reduce system integration costs.
SM Series
The SM Series provides a flexible alternative to semi-rigid cable, utilizing the same connectors and tooling. Ideal for military ECM, guidance systems, commercial antennas, and communication applications requiring compact or densely-spaced interconnects. Features double shield construction for >100 dB shielding effectiveness.
Superior Cable Technology
Semflex utilizes various jacket materials (Polyurethane, FEP) and dielectric materials (Polyethylene, Solid PTFE, Low Density PTFE, Ultra Low Density PTFE) selected for specific performance, temperature, and environmental requirements. Shielding options include single, double, and triple shield constructions with varying braid and foil combinations for optimized shielding effectiveness and flexibility.
Connectors
Semflex offers a wide selection of microwave connectors designed for excellent electrical transitions and low VSWR. They also provide custom connector designs for special requirements such as high power, environmental sealing, and low intermod characteristics.
