N M Solder for 1/4″ Super Flexible Cable

Description

The N-Type connector is the industry standard for high-reliability RF applications, prized for its mechanical strength and low attenuation. This male (plug) variant is specialized for the 1/4″ Super Flexible (Superflex) Cable class. Unlike standard feeder cables, superflex features a deep helical corrugation that provides an exceptionally tight bend radius. This connector utilizes a solder-on design, where the cable’s helical outer conductor is soldered directly to the connector body, creating a seamless, airtight 360-degree electrical bond.

By utilizing a solder termination instead of a mechanical clamp, this connector offers the lowest possible contact resistance and superior Passive Intermodulation (PIM) stability. This makes it an essential component for high-frequency testing, phase-matched cable sets, and high-density wireless systems where mechanical movement might otherwise affect signal purity. Manufactured with a heavy-duty tri-metal or silver-plated brass body and premium PTFE (Teflon) insulation, it delivers stable 50-Ohm performance and exceptionally low VSWR up to 18 GHz.

Key Technical Advantages

• Helical Corrugation Integration: The internal housing is precision-machined to match the helical threads of 1/4″ superflex cable, facilitating a clean solder flow and a permanent mechanical bond.

• Direct-Solder Integrity: Provides a 360-degree electrical path that significantly reduces insertion loss and signal leakage compared to mechanical or crimp-style terminations.

• Superior PIM Performance: The solid solder interface minimizes non-linearities, ensuring ultra-low Passive Intermodulation—critical for modern multi-carrier 5G and LTE infrastructure.

• Rugged Threaded Coupling: The 5/8-24 threaded interface provides a vibration-proof connection with high torque capability, ensuring stable performance in aerospace and tactical environments.

• High-Frequency Stability: Engineered to maintain high-grade performance up to 18 GHz, making it suitable for precision microwave measurements and broadband data transmission.
