Flexible Cable & Harness Assemblies
High-performance flex cable assemblies up to 110 GHz - .047, .086, .141 series with precision connectors
Southwest Cable Assemblies
Complete high-performance coaxial cable assemblies for laboratory, production test, and system integration
Southwest Microwave supplies complete high-performance .047, .086 and .141 flex cable assemblies up to 110 GHz. Available with direct solder cable connectors, field replaceable cable connectors, or multi-pin coax contacts. Every cable assembly is tested with full VSWR and insertion loss data provided. Custom cable lengths, phase matching, and ruggedized options are available for defense, space, and telecom applications.
Cable Series
Three cable diameters covering DC to 110 GHz
.047 Cable - 67 GHz
Ultra-low-loss, small-diameter coaxial cable. Available with 1.85mm and 2.92mm connectors. Ideal for高密度 PCB layouts and phase-array feed networks where space is limited.
.086 Cable - 90 GHz
Low-loss, semi-rigid and flexible options. Available with 1.35mm, 1.85mm, 2.40mm, and 2.92mm connectors. Excellent phase stability over temperature and bending.
.141 Cable - 110 GHz
Industry-standard diameter with excellent power handling. Available with 1.0mm, 1.85mm, 2.40mm, 2.92mm, and SMA connectors. Ruggedized and phase-matched options for aerospace and defense.
Connector Options
Precision connectors factory-installed on cable assemblies
Direct Solder Cable Connectors
Permanent solder attachment for maximum reliability. Eliminates connector-cable interface variation. Ideal for high-vibration and space applications.
Field Replaceable
Interchangeable connector interfaces on the same cable assembly. Enables in-field adapter replacement without special tools. Saves maintenance time and cost.
Multi-Pin Coax Contacts
Multi-coax pin contacts for blind-mate and rack-and-panel applications. Suitable for系统级 integration where multiple RF channels need simultaneous mating.
Test & Certification
Every cable assembly is 100% tested with full traceability
VSWR & Insertion Loss
Each assembly is tested across the full operating frequency. Test data (VSWR and insertion loss vs. frequency) is provided with the shipment.
Phase Matching
Phase-matched pairs and sets available with <±2° phase tracking. Essential for phased array and multi-channel RF systems.
Environmental Qualification
Optional temperature cycling, vibration, and humidity testing per MIL-PRF and ESCC standards. Space screening and DPA available.
