Description
The SMA Female 2-Hole Flange Connector for RG402 is a professional-grade RF component designed for secure panel mounting in high-performance environments. Unlike 4-hole variants, the 2-hole rectangular flange (often called a “Trimline” flange) offers a reduced footprint, allowing for higher connector density on equipment chassis and internal bulkheads.
Optimized for RG402 (.141″) semi-rigid cable, this connector utilizes a direct-solder body attachment. The cable’s solid copper outer conductor is soldered 360 degrees directly to the connector body, creating a seamless, gas-tight mechanical and electrical bond. This method ensures superior EMI/RFI shielding and minimizes signal leakage, making it ideal for RF power amplifiers, base stations, and precision test fixtures operating from DC up to 18 GHz.
Key Technical Advantages
-
Space-Efficient Mounting: The 2-hole flange allows for closer vertical or horizontal mounting centers on dense interface panels compared to square 4-hole versions.
-
Direct-Solder Shielding: Provides essentially 100% RF isolation by creating a continuous metal-to-metal bond between the cable jacket and connector.
-
Ultra-Low VSWR: Precision-machined internal geometry maintains a strict 50 Ohm impedance, ensuring high signal integrity and minimal insertion loss even at microwave frequencies.
-
Mechanical Stability: Once bolted to the chassis, the flange prevents the connector from spinning or loosening during antenna mating, protecting the internal solder joints.
-
Broad Frequency Range: Maintains exceptional performance across microwave frequencies from DC up to 18 GHz.
Key Features
-
2-Hole Rectangular Flange: Designed for flush mounting on panels using two standard M2 or M2.5 screws.
-
Direct-Solder Termination: Custom-bored to fit the .141″ diameter of RG402 and conformable equivalents perfectly.
-
Premium PTFE (Teflon) Insulator: High-purity dielectric ensures stable electrical performance and high heat resistance during the soldering process.
-
Gold-Plated Beryllium Copper Contact: Ensures low contact resistance and maximum durability for over 500 mating cycles.
-
Rugged Construction: Built from gold-plated brass or stainless steel for maximum conductivity and corrosion resistance.
