4.3-10 Mini DIN Tee-Type Adaptor (F-F-M), DC to 7.5 GHz

Description

The 4.3-10 Tee-Type Adapter (Female-Female-Male) is a precision RF component designed to branch a single signal path into two using one standard 4.3-10 Male interface and two 4.3-10 Female interfaces. As the modern successor to the larger 7/16 DIN interface, the 4.3-10 system provides exceptional Passive Intermodulation (PIM) performance in a significantly more compact footprint. Precision-machined to perform up to 7.5 GHz, this adapter is specifically optimized for the high-frequency requirements of 5G sub-6GHz deployments and high-power wireless infrastructure where space is at a premium.

The adapter features a Tri-Metal (White Bronze) plated Brass body for superior mechanical durability and low contact resistance. To ensure maximum signal fidelity, it utilizes Silver-Plated center contacts, achieving the ultra-low PIM ratings (≤ -161 dBc) required to prevent interference in sensitive cellular networks. The rugged threaded interface provides a secure connection that remains stable under mechanical stress. This specific F-F-M layout is ideal for mounting directly onto a piece of equipment’s female port, effectively splitting the output for simultaneous transmission and real-time monitoring.

Key Technical Advantages

• Ultra-Low PIM Performance: Engineered with independent electrical and mechanical contacts to ensure stable, low-PIM results even when subjected to vibration or torque.

• Compact High-Density Design: Provides high power handling in a small form factor, allowing for increased port density on modern 5G radio heads and small cells.

• Direct Component Interfacing: The single male port allows the adapter to be threaded directly onto female chassis ports, reducing cable clutter and signal path complexity in tight enclosures.

• Extended 7.5 GHz Bandwidth: Precision-tuned to support the latest 5G FR1 spectrum and future-proofed for evolving microwave and satellite communication bands.

• Weatherproof Tri-Metal Finish: The specialized white bronze plating offers exceptional corrosion resistance and RF shielding, suitable for both outdoor macro-cell and indoor DAS environments.
