Key Features and Benefits

Hermetic Sealing for Critical Environments

The hermetic design prevents moisture, gas, and contaminant penetration across mounting boundaries. This makes the connector suitable for vacuum chambers, pressurized enclosures, and sealed electronic modules. Your equipment maintains signal integrity even in extreme environmental conditions.

Microstrip Design for PCB Integration

The microstrip structure facilitates seamless transition between the connector and PCB microstrip lines. This design minimizes impedance discontinuity and reduces signal reflection. You benefit from lower insertion loss and improved high-frequency signal transmission in your RF circuits.

Compact, High-Density Mounting

The SSMA interface offers approximately 30% higher port density compared to standard SMA connectors. The dual-hole flange mount provides secure chassis or bulkhead installation. This configuration is perfect for applications where space optimization is essential without compromising performance.

Superior Electrical Performance

With VSWR below 1.05+0.012F(GHz) and insertion loss of ≤0.05√F(GHz)dB, the connector maintains excellent signal fidelity. The 50Ω impedance matching ensures minimal signal distortion. Your systems achieve reliable performance throughout the DC-30GHz frequency range.

Primary Applications

Aerospace and Satellite Systems

The SSMA Female Connector Hermetic Flange serves in satellite transponders and multiplexers where hermetic sealing maintains internal pressurization against space vacuum. The connector prevents outgassing and protects sensitive electronics in orbital environments.

Defense Electronic Warfare

Defense systems integrate these connectors into compact phased-array radar modules and electronic countermeasure equipment. The ruggedized hermetic seal withstands salt spray, humidity, and vibration typical of military deployment scenarios.

High-Precision Test and Measurement

Laboratory and telemetry systems use these connectors where signal integrity must cross pressure or temperature barriers. Applications include cryogenic sensors, high-altitude communication equipment, and vacuum test chambers requiring reliable RF feedthrough.

Quality Control and Testing

SIPU RF Technology adheres to strict quality processes to provide consistent results. Each manufacturing batch will be subjected to dielectric withstanding voltage testing utilising insulation testers to confirm 750V rating and insulation resistance > 1,000MΩ.

Quality inspection of plating validates coating thickness and adhesion strength for each batch. All goods are batch tested to RoHS environmental requirements. The manufacturing process follows the ISO 9001 quality management requirements, with continuous monitoring throughout the production run.

Frequently Asked Questions

Q: Hermetic flange design. What are its advantages?

A: Hermetic construction seals the product against the intrusion of moisture and contaminants. This means it operates reliably in vacuum settings, pressurised enclosures and extreme situations that ordinary connections would fail.

Q: What advantages does the microstrip structure provide for my application?

A. The microstrip design provides a seamless impedance transition from the connection to the PCB trace. This lowers signal reflections and insertion loss, especially significant for high frequency applications over 18GHz where impedance matching is required.

Q. What installation considerations do I have to follow?

A: Correct torque specs to prevent straining the hermetic seal. Make sure the mounting surface is clean and smooth. When mating, avoid side-loading the central pin to ensure seal integrity and electrical performance.

Q. Can this connection withstand excessive temperature cycling?

A: The operational temperature range is from -65℃ to +125℃. Material selection also assures the thermal expansion compatibility of components to preserve the hermetic seal integrity during temperature extremes characteristic of aircraft applications.

Q: How long should I expect it to last?

A: The connection can be mated and unmated 500 times with correct installation and care. The hermetic seal and gold plated connections guarantee long term durability in harsh situations when operated within limitations.
