SAA or 1.0/2.3 M Solder Type for LMR100/RG174/RG316 Cable

Description

The SAA series, commonly referred to as the 1.0/2.3 connector, is a subminiature RF interface designed for high-density environments where signal precision is a mechanical necessity. This male (plug) solder-type variant is specifically optimized for micro-diameter cables, including the low-loss LMR100, flexible RG174, and high-temperature RG316. Unlike all-crimp versions, the solder-type center contact provides a fused, low-resistance electrical bond, which is preferred for sensitive digital telephony circuits (E1, E3, DS3) and professional video applications where maximum signal transparency is required.

Maintaining a strict 75-Ohm impedance, this connector is essential for preventing signal reflections and bit errors in high-speed data transmission. The push-pull coupling mechanism allows for quick, tool-free mating with a secure tactile “lock,” enabling rapid deployment in high-port-count hardware. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional electrical stability and superior protection against environmental oxidation in central office exchange environments and rack-mounted equipment.

Key Technical Advantages

• Permanent Solder Termination: The solder-cup center contact provides a high-conductivity fused connection, offering superior electrical permanence and lower contact resistance compared to crimp pins.

• Micro-Cable Precision Fit: Specifically calibrated for the dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring an optimized electrical transition and minimal return loss.

• Ultra-High Density Footprint: The compact 1.0/2.3 interface allows for significantly higher port density on equipment panels than traditional 75-Ohm connectors like BNC or SMZ.

• Push-Pull Coupling Mechanism: Features a secure, vibration-resistant mating system that provides a distinct tactile click, ensuring a complete and reliable electrical path without the need for tools.

• Superior Corrosion Protection: Premium gold-over-nickel plating on all critical surfaces ensures long-term durability and low contact resistance in professional infrastructure.

Key Features

• Interface Type: SAA / 1.0/2.3 Male (Plug) with 75-Ohm impedance.

• Termination Method: Solder center contact with a high-strength outer crimp ferrule for mechanical strain relief.

• Cable Compatibility: Optimized for LMR100, RG174, and RG316 coaxial cables.

• Premium Construction: Features a gold-plated brass body and a high-performance PTFE dielectric for thermal stability during soldering.

• Industrial Application: Ideal for high-density Digital Distribution Frames (DDF), telephony racks, and modular broadcast exchange equipment.
