Precision RF interconnects for mission-critical defense systems.
We build RF coaxial cable, connectors and cable assemblies for radar, electronic warfare and military communication systems — engineered to hold their specification in extreme conditions.
Built for signals that can't fail.
Founded in 2013, Kaelen Microwave Technologies designs and manufactures RF, microwave and millimeter-wave interconnects — coaxial cable assemblies, connectors from standard bands to 110 GHz, precision attenuators and passive components — for defense, aerospace and telecommunications customers worldwide.
Every assembly follows a zero-defect policy: 100% sweep testing for VSWR, insertion loss and phase matching, with individual serialization and a test report per unit. Certified to ISO 9001:2015 and AS9100D, compliant with MIL-DTL-17, MIL-STD-202 and MIL-STD-810H.
