Description
The SMA Female 4-Hole Flange Connector for RG141 is a precision RF interface used for mounting through enclosure walls or onto internal bulkheads. Unlike standard bulkhead connectors that use a single nut, the 4-hole square flange provides superior mechanical stability and prevents rotation or movement during high-torque antenna mating.
Optimized for RG141 (.141″) semi-rigid cable, this connector utilizes a direct-solder mounting process. The cable’s solid copper outer conductor is soldered 360 degrees directly to the connector body. This creates a seamless, airtight bond that ensures the highest level of EMI/RFI shielding and minimizes Passive Intermodulation (PIM), making it the industry standard for high-power transmitters and precision test laboratory equipment up to 18 GHz.
Key Technical Advantages
-
Exceptional Mechanical Stability: The 4-hole square flange allows for secure mounting with four screws, distributing physical stress evenly across the chassis surface.
-
Seamless 360° Shielding: The direct-solder bond between the cable jacket and connector body provides nearly 100% RF isolation.
-
Ultra-Low VSWR: Precision-machined internal geometry maintains a consistent 50 Ohm impedance, crucial for minimizing signal loss in high-frequency microwave paths.
-
Thermal Reliability: The solder-on design handles thermal expansion and contraction better than crimp or clamp connectors in extreme environments.
-
Premium Gold Plating: Features high-purity gold plating over brass or stainless steel for maximum conductivity and long-term corrosion resistance.
Key Features
-
4-Hole Square Flange: Allows for flush mounting on panels and provides a vibration-proof mechanical anchor.
-
Direct-Solder Termination: Custom-bored for a perfect fit with RG141, RG402, and .141″ semi-rigid cable.
-
High-Purity PTFE Insulator: Premium Teflon dielectric ensures stable electrical performance and high heat resistance during soldering.
-
Standard SMA Female (Jack): Features internal threads and a gold-plated beryllium copper socket.
-
Microwave Frequency Support: Designed for reliable operation from DC up to 18 GHz.
