SSMA Female to SMA Female Adapter

SSMA Female to SMA Female Adapter – Precision RF Interconnect Solution

SIPU RF Technology Co., Ltd. manufactures high-performance SSMA Female to SMA Female Adapter (Model: SIPU-SSMA/SMA-KK) designed for critical RF and microwave applications requiring reliable inter-series connectivity. This precision adapter bridges miniaturized SSMA interfaces with standard SMA connections, operating across DC to 18 GHz with characteristic impedance of 50Ω. Featuring gold-plated beryllium bronze center contacts and brass outer conductors, the adapter delivers insertion loss of ≤0.05√F(GHz)dB and VSWR of ≤1.05+0.012F(GHz). With 500 mating cycles durability and operating temperature range from -65℃ to +125℃, this enterprise-grade solution ensures consistent performance in demanding telecommunications, aerospace, and test environments where space optimization meets high-frequency requirements.

What Makes This Adapter Essential for Your RF System

The SSMA Female to SMA Female Adapter solves a critical interconnectivity challenge in modern RF systems. SSMA (Sub-Small Micro-A) connectors feature a 10-36 UNS thread, significantly smaller than the standard SMA's 1/4-36 UNS thread. This size difference makes direct connection impossible.

Your high-density microwave modules and compact test setups demand reliable conversion between these interface standards. This adapter enables seamless integration between miniaturized SSMA-equipped devices and standard SMA test equipment.

The straight orientation design maximizes compatibility with tight installation spaces. Your signal integrity remains uncompromised through precision-engineered mechanical transitions.

Key Performance Advantages

Your RF systems benefit from multiple design advantages built into this adapter. The SSMA interface supports higher-frequency applications with lower insertion loss compared to conventional miniature connectors.

Gold-plated beryllium bronze center contacts maintain low contact resistance throughout the adapter's 500-cycle service life. This material selection ensures consistent electrical performance under repeated mating conditions.

PTFE dielectric material provides stable signal transmission across the full DC-18GHz frequency range. Your measurements remain accurate even under thermal stress from -65℃ to +125℃.

The compact design integrates seamlessly into high-density RF modules. You gain space efficiency without sacrificing connection reliability or signal quality.

Each production batch undergoes plating quality inspection, including thickness and bonding force verification. RoHS environmental compliance testing ensures regulatory adherence for global applications.

Primary Application Environments

Aerospace and Defense Systems

Your satellite communication payloads and compact radar modules require lightweight, space-efficient interconnects. This adapter connects SSMA-equipped flight hardware to standard SMA ground support equipment.

The robust construction withstands high-vibration environments common in aerospace applications. Your signal paths remain stable through demanding operational conditions.

RF Testing and Measurement

Laboratory engineers connect miniaturized PCB-mounted SSMA devices to vector network analyzers using standard SMA cables. This adapter enables accurate calibration without signal degradation.

You maintain measurement precision across the full frequency range. The low VSWR specification minimizes reflection errors in sensitive test configurations.

Telecommunications Infrastructure

High-density 5G base station modules benefit from SSMA's compact footprint. This adapter facilitates integration with existing SMA-based test equipment during installation and maintenance.

Your field technicians gain flexibility when servicing mixed-interface systems. The adapter eliminates costly cable assembly redesigns.

Quality Control and Testing

SIPU RF Technology implements rigorous quality verification for every adapter batch. Insulation and dielectric withstanding voltage testing uses specialized instruments to verify 750V capability and ≥5,000MΩ insulation resistance.

The adapter's structural design inherently ensures VSWR and insertion loss performance. You receive consistent electrical characteristics verified through precision manufacturing processes.

Plating quality inspection monitors gold layer thickness and bonding force for each production lot. This proactive approach prevents premature contact degradation.

Environmental compliance testing confirms RoHS adherence. Your procurement teams can specify these adapters with confidence in regulatory compliance.

Frequently Asked Questions

Q:What frequency range does this product support?

A:The adapter operates from DC to 18 GHz with specified VSWR and insertion loss performance. This range covers most commercial telecommunications and aerospace applications.

Q:Are SSMA and SMA threads compatible without an adapter?

A:No. SSMA uses 10-36 UNS threading while SMA uses 1/4-36 UNS. Attempting direct connection will damage both connectors. This adapter provides the only safe interconnection method.

Q:What installation precautions should you observe?

A:Hand-tighten connections first, then apply appropriate torque. The smaller SSMA interface requires careful handling to prevent thread damage. Always inspect threads before mating.

Q:Can this adapter work in extreme temperature environments?

A:Yes. The -65℃ to +125℃ operating range accommodates most environmental test chambers and outdoor installations. PTFE dielectric maintains stable properties across this thermal range.

Q:How does this adapter affect signal phase?

A:Like all RF interconnects, the adapter introduces measurable phase delay. For phase-matched applications, source multiple adapters from the same production batch and verify performance with vector network analysis.
