Custom RF Cable Assembly Capabilities

EI Sales provides high-performance RF cable assemblies engineered to meet the electrical, mechanical, and environmental demands of critical systems. Our team supports you from initial concept through production, helping you select the right materials, impedance specs, shielding, and connectors to ensure signal integrity and performance.

We support a wide range of configurations:

  • Coax types: RG, low-loss, semi-rigid, micro-coax

  • Connector options: SMA, MMCX, BNC, TNC, N-type, U.FL

  • Impedance-matched and phase-matched assemblies

  • Overmolded, strain-relieved, and right-angle designs

Every assembly is fully tested for continuity, insertion loss, and impedance to ensure field readiness. At EI Sales, we offer more than components, we provide integration-ready RF solutions tailored to your performance goals, with support spanning design through final test.

Built for Demanding Environments

Our RF cable assemblies are designed and tested for use in mission-critical environments where signal stability and mechanical integrity are non-negotiable. Inside sterilized surgical instruments, and factory-floor control cabinets, EI Sales provides assemblies that meet tight tolerances and harsh-duty requirements. 



Assemblies can be specified to withstand wide temperature ranges, vibration, chemical exposure, and moisture ingress, with optional IP-rated sealing or braided shielding for added protection. We also offer low-PIM solutions for high-frequency and interference-sensitive environments. 

Lastly, every assembly is manufactured with quality in mind, including 100% testing for continuity, insertion loss, and VSWR. When reliability is the baseline, EI Sales delivers cables that perform under pressure.

RF Assemblies Tailored to Your Application Needs

No two applications are alike. EI Sales works closely with engineers, program managers, and sourcing teams to provide custom RF assemblies tailored to system-level performance and integration requirements. 

Our solutions include:



  • Medical: Miniature coax for telemetry and imaging, biocompatible options

  • IOT: Quick uptime and high volume production capability to support volatile demands 

  • Industrial: Durable assemblies for control cabinets, machinery, and robotics

For projects with tight routing constraints, impedance matching, or shielding challenges, we provide expert guidance on layout, connector interface, and cable selection. We’ll help you create RF assemblies that are ready for deployment, not just bench testing

What our partners say

I just wanted to let you know that the five prototypes of the Glove 3.0 Main Board you built worked great. No errors and completely functional. Another exceptional job.  Please let everyone know that this is why I use Ninja for our prototypes. I believe you have or will be receiving the P.O. for the remaining 25 units.
