Data Alliance supplies RP-SMA male connectors designed for terminating coaxial antenna cables used in WiFi, cellular, and IoT systems. These connectors feature the reverse polarity interface commonly required for wireless equipment, ensuring proper compatibility with RP-SMA female jacks.

Design Characteristics

• Internal threads
• Female center contact (no pin)
• Engineered for consistent impedance and reliable signal transfer
• Commonly installed on coax cable assemblies and antenna leads

Construction Options

Brass-Plated Copper

• Strong electrical conductivity
• Economical choice for indoor installations
• Suitable for controlled environments

Nickel-Plated Brass

• Added protection against oxidation and corrosion
• Better suited for outdoor or variable environmental conditions
• Maintains mechanical integrity over time

Cable Compatibility

Available for precise termination with:

• LMR-100 – compact, flexible coax for space-limited designs
• LMR-200 – mid-size cable for general-purpose RF connections
• LMR-400 – low-loss cable for longer distance signal runs

Each connector is sized for proper fit and shielding effectiveness with the specified cable.

Typical Use Cases

• Antenna cable assemblies
• WiFi and access point connections
• Cellular modem and router cabling
• Embedded wireless systems

Key Advantages

• Reliable threaded coupling
• Stable electrical performance
• Multiple plating options based on environment
• Compatible with industry-standard RP-SMA interfaces

Important Note

RP-SMA male connectors use a socket (no center pin), which differs from standard SMA male connectors. Verify compatibility before ordering.

Custom Cable Assemblies Available

Data Alliance can provide RP-SMA male connectors pre-installed on custom cable assemblies, built to your specifications.
