SMA Male Right Angle Solder Cable Assembly Specifications

Design Features and Engineering Excellence

The right-angle design of this SMA Male Right Angle Solder Cable Assembly addresses critical spatial constraints in modern RF systems. The 90° configuration minimizes cable bending stress while facilitating efficient routing in densely populated equipment racks and PCB assemblies.

SIPU's precision manufacturing ensures uniform termination and consistent signal behavior across every assembly. The solder-type mounting method provides superior electrical performance compared to crimp alternatives, particularly at frequencies above 6 GHz. This results in lower passive intermodulation and enhanced signal integrity.

The outer conductor is made of gold plated brass or passivated stainless steel that has exceptional corrosion resistance and maintains low contact resistance throughout the life of the assembly. The dielectric material used is PTFE that offers the low loss and thermal stability needed for high frequency applications.

Semi-steel cable shielding provides optimum protection against electromagnetic interference and yet allows for flexibility in installation. Each assembly is tested with insulation resistance testers to validate 1,000V capability and >5,000 MΩ insulation resistance in dielectric withstanding voltage tests.

Quality Assurance Process

SIPU implements comprehensive quality control protocols to ensure every SMA Male Right Angle Solder Cable Assembly meets stringent performance standards. Each production batch undergoes systematic inspection procedures aligned with ISO 9001 requirements.Meet RoHS.

Electrical performance verification includes using calibration equipment to conduct frequency, standing wave, insertion loss, phase, dielectric withstand voltage, insulation resistance, etc. tests. 100% tested to confirm compliance with specified requirements.

Batch-level quality audits include plating thickness measurement and plating adhesion testing to verify coating integrity. RoHS environmental compliance testing is performed on each production batch to ensure regulatory conformance.

Mechanical interface gauging verifies dimensional accuracy to prevent damage to mating connectors. Visual inspection confirms solder joint quality and proper cable termination. This multi-stage verification process guarantees consistent performance and long-term reliability.

Application Environments

The low size of this right-angle assembly makes it ideal for telecommunications infrastructure. The SMA Male Right Angle Solder Cable Assembly enables high-density port configurations for 5G base stations and MIMO antenna arrays while maintaining signal integrity. Space saving design for equipment cabinets for effective cable management.

These assemblies are used in aerospace and defence systems in radar modules and electronic warfare equipment where internal volume is at a premium. Rugged design resists vibration and temperature cycling experienced in airborne and mobile platforms. Wide operation temperature range -65℃ to +125℃ provides the dependable performance under harsh climatic conditions.

These assemblies are included into spectrum analysers, network analysers, and oscilloscopes by test and measurement equipment makers. The phase consistency of phase ≤±5° between internal PCB components and front-panel connectors makes the right-angle configuration an ideal choice for stable signal paths for accurate measurement results.

Industrial electronics applications include wireless communication devices, RF signal generators and microwave test equipment where repeatable performance and mechanical ruggedness are essential.

Installation and Compatibility

The solder-type mounting method requires proper soldering techniques to achieve optimal electrical and mechanical performance. Controlled temperature profiles and appropriate solder alloys ensure strong joints without thermal damage to the cable dielectric or connector components.

The assembly is specifically engineered for use with SFT-50-2-1 semi-steel cable. This pairing ensures impedance matching and consistent electrical characteristics throughout the signal path. Custom cable lengths beyond the standard 150 mm are available upon request to accommodate specific installation requirements.

Your installation should account for the minimum bend radius specifications of the cable to prevent performance degradation. The right-angle design inherently reduces stress on the cable at the connector interface, contributing to extended service life.

Frequently Asked Questions

Q:What advantages does the solder-type connection offer?

A:Solder-type connections provide superior electrical performance with lower passive intermodulation at frequencies above 6 GHz compared to crimp connections. The soldered interface creates a more uniform impedance transition.

Q:How does the right-angle configuration affect signal integrity?

A:When properly engineered, the right-angle bend introduces minimal impedance discontinuity. SIPU's optimized internal geometry compensates for the 90° transition, maintaining VSWR below 1.3 across the full frequency range.

Q:What is the power handling capacity?

A:Power handling depends on frequency and cable type. Semi-rigid assemblies typically handle 100W to 500W at 1 GHz, with capacity decreasing at higher frequencies due to increased conductor losses.

Q:Can this assembly be used in outdoor environments?

A:Yes, when properly sealed. The gold-plated and passivated finishes provide corrosion resistance. However, additional environmental protection may be required for direct weather exposure.

Q:What testing is performed on each assembly?

A:Every unit undergoes dielectric withstanding voltage testing and insulation resistance verification. Batch-level audits include plating quality inspection and RoHS compliance testing to ensure consistent quality.
