Frequently Asked Questions
Q: What is an N-Type fixed RF attenuator used for?
A: An N-Type fixed RF attenuator is a passive coaxial component used to reduce signal power by a precise, fixed amount (measured in dB). It is commonly used in RF testing labs, antenna systems, SDR setups, and ham radio stations to control signal levels, protect sensitive components, or match power levels between different parts of an RF chain.
Q: What frequency range does this RF attenuator support?
A: This fixed coaxial attenuator operates from DC up to 4 GHz, making it suitable for a broad range of RF and microwave applications including Wi-Fi, cellular, UHF/VHF, and general lab use.
Q: What attenuation values and power ratings are available?
A: Available attenuation values include 3 dB, 5 dB, 6 dB, 10 dB, 15 dB, 20 dB, 30 dB, and 40 dB. Power ratings range from 2W and 5W for lighter-duty applications up to 10W and 20W for higher-power RF systems. Please select your required combination when ordering.
Q: Is this attenuator compatible with standard 50-ohm RF systems?
A: Yes. This N-Type coaxial attenuator is designed with a 50-ohm impedance, which is the industry standard for most RF test equipment, transceivers, and antenna systems, ensuring minimal VSWR and maximum power transfer efficiency.
