Low Insertion Loss Semi-Rigid SMP Cable Assembly CASE STUDY Customer Challenge Winchester was asked to evaluate cable assemblies that failed to consistently meet the customer’s expected performance levels. The customer manufactured the assemblies in-house using purchased MIL Spec SMP Right-Angle solder type cable connectors with a standard bifurcated center contact. The customer selected 0.047 semi-rigid cable with 69.5 VoP solid PTFE dielectric. Coupling the connector and cable with the quality assembly work from experienced operators, the customer should have been able to meet the required performance criteria. However, despite its best efforts the customer could not reliably pass a 0.70 dB Insertion Loss and 1.35:1 VSWR @ 20 GHz requirement. This inconsistency was causing cri
