Design Features and Benefits

The extended bulkhead design of this product addresses your specific installation challenges. The flange-mount structure provides mechanical stability when mounting through thick chassis walls or multi-layered EMI-shielded enclosures.

The microstrip PCB launch configuration enables direct transition from coaxial to planar transmission lines. This design reduces signal path loss and simplifies your high-density circuit board layouts. You benefit from a compact footprint that saves valuable board space in miniaturized RF modules.

Gold plating on both the brass outer conductor and beryllium bronze center contact delivers superior corrosion resistance and low contact resistance. The PTFE dielectric maintains stable electrical performance across the full temperature range. These material choices ensure consistent performance throughout 500 mating cycles.

The straight orientation and female interface gender make this connector ideal for panel-mount applications. Your installation teams will appreciate the secure mounting that the extended threads provide through thick walls.

Industrial Applications

Aerospace and satellite systems utilize this SSMA Female Connector Extended Bulkhead Microstrip in transponders and phased array antennas. The extended bulkhead allows mounting through structural panels while maintaining hermeticity and vibration resistance under extreme conditions.

Defense and electronic warfare modules rely on this connector for compact signal processing applications. The microstrip transition remains stable under high G-force loads and thermal shock, ensuring mission-critical reliability.

High-speed semiconductor testing equipment incorporates these connectors in automated test fixtures. The robust interface connects test instruments to high-frequency evaluation boards through thick thermal-insulation plates in environmental test chambers. You gain stable measurements even in demanding test conditions.

Telecommunications infrastructure, research laboratories, and precision measurement systems also benefit from the connector's high-frequency capabilities and reliable performance.

Quality Control Process

Your product quality concerns are addressed through SIPU's comprehensive inspection protocols. Each batch undergoes dimensional metrology verification to confirm precise thread tolerances and microstrip pin protrusion lengths.

Electrical performance testing utilizes insulation withstanding voltage testers to verify dielectric strength and insulation resistance per specification. Every batch receives plating quality inspection, measuring both coating thickness and adhesion strength. This ensures the gold plating maintains its protective and conductive properties throughout the connector's service life.

Environmental compliance testing confirms RoHS certification for each production batch. You receive connectors that meet international environmental standards for conflict-free materials and reduced hazardous substances.

SIPU's quality management follows ISO 9001 certification standards. Our manufacturing facility implements strict process controls from raw material inspection through final product verification.

Frequently Asked Questions

Q:Can I mate this SSMA connector with standard SMA connectors?

A:No, SSMA uses a smaller 10-36 UNS thread compared to SMA's 1/4-36 thread. Attempting to mate them will cause permanent damage to both connectors.

Q:What advantages does the extended bulkhead provide?

A:The extended thread length allows installation through thick-walled or multi-layered housings where standard bulkhead connectors lack sufficient thread engagement for proper mounting hardware.

Q:How should I design the PCB microstrip transition?

A:Optimize your PCB landing pad dimensions and use appropriate matching techniques to minimize parasitic capacitance at the connector-to-board interface. Proper transition design maintains signal integrity at high frequencies.

Q:What is the recommended mating torque?

A:Apply 3 to 5 in-lbs (0.34 to 0.57 Nm) using a calibrated torque wrench. Correct torque ensures repeatable electrical performance and extends connector life to the full 500 mating cycles.

Q:Is this connector suitable for space applications?

A:Yes, when specified with low-outgassing PTFE dielectric, the connector can meet stringent vacuum environment requirements for aerospace applications.
