N-Type Terminators

At Amphenol RF, our N-Type terminator family provides designers and engineers with a trusted solution for properly terminating unused ports or cable ends in RF systems that utilise the N-Type threaded connector interface.

With the N-Type interface being widely adopted in broadcast, telecom, instrumentation and wireless infrastructure markets, the Amphenol RF N-Type terminators support robust mechanical performance, high-quality RF consistency and a comprehensive part portfolio for both standard and extended-frequency applications. The connector series also boasts performance from DC up to 11 GHz (and up to 18 GHz in extended range designs) in the broader N-Type connector family.

Features and Benefits

• Industry-standard N-Type interface ensures compatibility with a broad range of RF equipment, cable assemblies and infrastructure, simplifying sourcing and integration.
• 50 Ω impedance (standard for N-Type series) aligns with most RF transmission systems and termination requirements, ensuring proper mismatch control and signal integrity.
• Threaded coupling mechanism provides strong, vibration-resistant connections suitable for outdoor, mobile and harsh-environment applications—a benefit inherited from the N-Type connector lineage.
• Broad frequency support via the underlying connector family enables termination solutions suited for high-frequency system segments, including some extended-range parts up to ~18 GHz.
• Comprehensive part portfolio including plug and jack versions, different wattage ratings and chain-or-no-chain options make it easier to select the right termination for your deployment.

Key Technical Details

• Impedance: Standard 50 Ω (as listed in Amphenol RF’s N-Type terminator product page: e.g., part 202109-10 is 50 Ω).
• Frequency Range: The N-Type connector series supports DC – 11 GHz typically and up to DC – 18 GHz in extended-range designs. For terminators, performance is cable- and configuration-dependent.
• Mating Cycles: The N-Type connector family is rated for a minimum of approximately 500 mating cycles under standard conditions. For fixed terminator use, actual cycles may vary depending on environment and usage.
• Temperature Range: Typical operational range for the connector family is about –65 °C to +165 °C. The exact rating for a specific terminator depends on materials, finish and termination style.
• Special Features: Threaded coupling, high-density performance in standard form-factor, extended-frequency variants available. Note: Standard N-Type terminators from Amphenol RF are not described in the product listing as hermetically sealed or specifically IP67 rated unless indicated in the datasheet.

Applications

• Termination of unused RF ports in base-station and wireless infrastructure equipment where the N-Type interface is standard, ensuring signal path integrity and minimizing reflections.
• Broadcast, cable-distribution or instrumentation systems employing N‐Type connectors where terminated ports must maintain proper match and prevent system degradation.
• Outdoor or rugged enclosures and rack systems where the threaded N-Type coupling provides durable mechanical connection and termination performance under environmental stress.
• Test and measurement equipment requiring stable 50 Ω terminations for calibration, measurement and unused port isolation.
• RF network installations for telecom, radar, satellite or WLAN systems where engineers rely on a standard form-factor termination solution from a trusted supplier.
