SMP Male Straight Thread Mount Connector

SMP Male Straight Thread Mount Connector 

The SIPU RF Technology SMP Male Straight Thread Mount Connector   (SIPU-SMP-JYD14G)  Provides enterprise-grade performance in mission-critical RF systems running up to 40 GHz. This connection is designed with military grade accuracy, a characteristic impedance of 50Ω and a VSWR of ≤1.1 + 0.01F(GHz) for low signal reflection over the whole frequency range. The insertion loss is just <=0.07√F(GHz) dB, which means that it protects the signal integrity in high frequency applications. The connection is designed with a threaded mount that offers mechanical stability for >500 mating cycles and operates in temperatures from -65°C to +125°C. This product is manufactured to MIL and IEC standards with The inner contact is made of gold-plated beryllium bronze, and the outer conductor is constructed from passivated stainless steel with excellent corrosion resistance. It operates steadily and reliably in aerospace, defence equipment and high-end telecommunications infrastructure.

SMP Male Straight Thread Mount Connector Specifications

Materials and Construction

Quality materials define the reliability of your RF interconnect solution. The outer conductor utilizes passivated stainless steel, providing exceptional corrosion resistance and long-term durability in harsh environments.

The center conductor features beryllium bronze with gold plating. This combination ensures low contact resistance and superior electrical conductivity. Gold plating prevents oxidation and maintains stable performance throughout the connector's service life.

PTFE serves as the insulating medium. Its excellent dielectric properties maintain signal integrity across the full 40 GHz frequency spectrum. This material choice guarantees consistent electrical performance across extreme temperature ranges.

Key Performance Advantages

The straight configuration minimizes signal path complexity. This design reduces insertion loss and maintains phase stability in high-frequency applications. Your system benefits from more predictable signal behavior.

Threaded mounting delivers mechanical advantages over snap-on alternatives. The secure attachment withstands vibration and mechanical stress. You gain installation confidence in mobile platforms and high-vibration industrial settings.

Compact dimensions support high-density layouts. The straight configuration enables vertical mounting to maximize module space utilization. This feature is critical for designing modern RF modules where space is at a premium.

The connector maintains electrical performance in extreme conditions. Salt spray resistance of 96 hours demonstrates its suitability for marine and outdoor applications. Wide temperature tolerance ensures operation in both arctic and desert deployments.

Primary Application Environments

Aerospace and defense systems demand uncompromising reliability. The SMP Male Straight Thread Mount Connector serves in phased array radar systems, satellite communication payloads, and electronic warfare equipment. Its threaded mount ensures connections remain secure during launch vibrations and tactical maneuvers.

5G infrastructure and test equipment benefit from the connector's high-frequency capabilities. Automated test equipment (ATE) utilizes these connectors in high-port-density configurations. You achieve faster throughput in production testing environments.

Research laboratories and scientific instruments require precision. The connector's low VSWR and insertion loss preserve measurement accuracy. High mating cycle durability supports repeated connections in experimental setups.

Industrial electronics increasingly operate at higher frequencies. RF modules in industrial IoT, smart manufacturing, and autonomous vehicles rely on stable connections. The thread mount provides mechanical security in environments with constant motion.

Quality Control and Testing

SIPU RF Technology implements rigorous inspection protocols for every connector. Dimensional metrology verifies thread pitch and mechanical tolerances. Automated optical inspection ensures conformance to design specifications.

Electrical testing includes dielectric withstanding voltage verification at 500V. Insulation resistance measurement confirms values exceed 5,000 MΩ. Contact resistance testing validates both center and outer conductor performance.

Environmental screening includes thermal cycling across the full operating range. Salt spray testing runs for 96 hours to verify corrosion resistance. Each production batch undergoes RoHS environmental compliance testing.

Plating quality receives particular attention. Layer thickness measurement and adhesion testing ensure gold plating meets durability requirements. This attention to surface treatment prevents premature wear and maintains electrical performance.
