2981-1-1 : SC

SC Panel Jack (Keyed 42 degrees)

Winchester’s KINGS® brand SC series RF connectors are a medium-size, threaded coupling version of the C connector. They basically handle coaxial cables from .350” to .450” OD. However, designs accommodate .078” to .875” cables. Frequency range is 0 – 11 GHz. The SC connector is a 50 Ohm nominal impedance connector using an overlapping dielectric interface and is weatherproof. SC connectors are used in severe environments and are popular in aircraft and high vibration applications. They are covered under MIL-PRF-39012.

  • High Power RF Cables and Connectors

    An aerospace customer approached Winchester Interconnect with a challenge related to RF transmission lines it was using on a military surveillance aircraft radar system. The application met specifications established by the Electronic Industrial Alliance (“EIA”) and utilized EIA flange connectors to connect high power coaxial transmission lines with feedline diameters up to several inches. Although the current solution was functional, it was difficult to use, heavy, and inflexible. In addition, the existing solution had a limited number of possible configurations and was prone to foreign object debris (“FOD”).

  • Triple Shielded Cable Solution

    A customer approached Winchester Interconnect looking to improve the performance of its RF cables. The cables were used in automated test equipment where electromagnetic interference (“EMI”) was high. In addition, its assembly technicians complained that routing standard, double- shielded RF cable through its test system was difficult and would lead to delays in production.

  • Low Insertion Loss Semi-rigid SMP Cable Assembly

    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 critical disruptions in manufacturing.
