N-Type Attenuators

At Amphenol RF, our N-Type attenuator family offers engineers and RF system integrators a robust set of fixed attenuation modules built around the N-Type connector interface. These products are designed to deliver flat attenuation over the specified frequency band, integrate seamlessly into coaxial cable assemblies or test rigs, and support system calibration, signal-level management and circuit protection.

As part of a broad RF interconnect platform, N-Type attenuators from Amphenol RF provide compatible dimensions, trusted performance and global availability—allowing system designers to incorporate attenuation values of 3 dB, 6 dB, 10 dB, 15 dB, 20 dB and 30 dB in a standardized N-Type footprint.

Features and Benefits

• Flat-attenuation design: These attenuators feature microwave-grade resistor networks that consistently reduce signal power across the specified band for predictable system behaviour.
• Industry-standard 50 Ω impedance and N-Type interface: Ensures compatibility with standard RF systems, reducing the risk of mismatch or reflection.
• Range of attenuation values (3, 6, 10, 15, 20, 30 dB): Provides flexibility to adjust signal levels, protect downstream stages, or calibrate system components.
• Rugged coaxial format with hex flats on body: Supports secure mechanical torque installation and robust performance in lab or field environments.
• Backed by Amphenol RF’s product ecosystem: Offers clarity in part selection, global availability, and broad support for RF interconnect needs.

Key Technical Details

• Impedance: 50 Ω nominal for all standard N-Type attenuator parts.
• Frequency Range: Attenuator parts are specified up to ~6 GHz in standard catalog items, with broader ranges in some designs.
• Mating Cycles: The N-Type connector family specifies a minimum of ~500 mating cycles; actual attenuator durability may vary with use-environment and torque practices.
• Temperature Range: Typical N-Type product rated for –65 °C to +165 °C; specific attenuator part may have narrower limits—refer to datasheet.
• Special Features: Fixed attenuation in 50 Ω format, standardized N-Type interface, microwave-grade resistor construction. Note: These attenuators are not listed as hermetically sealed or IP67 rated unless the part documentation explicitly states so.

Applications

• Signal-level control in RF front-end modules, including receiver chains or transmitter paths, where precise attenuation is required.
• Protecting sensitive amplifier or converter stages from excess input power by inserting the correct attenuation.
• Calibration and test systems in RF labs where known attenuation values enable accurate measurement and verification workflows.
• Cable-assembly integration and interconnect systems where an inline attenuator is required to adjust signal amplitude without adding complex components.
• Wireless infrastructure, broadcast, radar, instrumentation or other platforms using the N-Type connector interface where attenuation modules must conform to the same mechanical footprint and impedance standard.
