Description
The SMA Male Straight Crimp Connector for LMR300 is a precision RF component designed for applications that require a robust mechanical and electrical connection. LMR300 is a popular low-loss cable choice, and this connector is sized to accommodate its unique dimensions, including the 0.94mm center conductor and 3.22mm armored material.
The termination process utilizes a hex-crimp method for both the center pin and the outer ferrule. This creates a permanent, 360-degree bond that provides a strong 27 lbs retention force, ensuring the cable remains secure even in high-vibration environments. Constructed with a gold-plated brass body and PTFE (Teflon) insulation, it maintains excellent signal integrity and a low VSWR of 1.15:1 across frequencies ranging from DC up to 3 GHz (with some precision models reaching 6 GHz).
Key Technical Advantages
-
Optimized for Low-Loss Cable: Specifically designed for the dielectric and shield diameters of LMR300, ensuring a perfect fit and preventing signal leakage.
-
Superior Conductivity: Features a gold-plated center pin and body, providing low contact resistance and maximum protection against oxidation.
-
High-Strength Mechanical Bond: The crimp-on ferrule ensures a rugged attachment that resists physical strain, far outperforming twist-on alternatives.
-
Excellent RF Shielding: The 360-degree ferrule crimp provides a continuous ground path, significantly reducing EMI/RFI interference.
-
Broad Environmental Tolerance: Designed to operate efficiently in temperatures from -40?C to +85?C, suitable for both indoor and outdoor installations.
Key Features
-
Hex-Crimp Termination: Provides a fast, reliable, and uniform attachment for both the center conductor and braided shield.
-
Teflon (PTFE) Dielectric: Ensures high-purity signal transmission and exceptional thermal stability during field assembly.
-
Standard 1/4-36 Threaded Nut: Guaranteed compatibility with all standard SMA female jacks and bulkhead adapters.
-
High Frequency Support: Reliably handles signals for 4G/LTE, 5G, GPS, and WiFi applications.
-
Industrial Durability: Rated for at least 500 mating cycles while maintaining consistent electrical performance.
