TNC Attenuators
TNC Attenuators are precision RF and microwave components designed to reduce RF signal power while maintaining accurate impedance matching and excellent signal integrity. These attenuators are widely used in telecommunications, aerospace, defense, radar systems, satellite communication, RF laboratories, wireless communication, industrial automation, and microwave testing applications where controlled signal attenuation is essential. Supporting frequencies from DC to 18 GHz, TNC Attenuators provide low VSWR, excellent return loss, stable attenuation, and reliable performance for demanding RF and microwave systems.
At SRFS Teleinfra, we manufacture premium-quality TNC Attenuators using precision resistive networks, premium TNC connectors, and advanced CNC machining technology to ensure excellent electrical performance, accurate attenuation, and long operational life. Our attenuators are suitable for RF testing, production testing, telecom infrastructure, aerospace communication, defense electronics, and industrial RF systems.
All our TNC Attenuators are manufactured in India under stringent quality control procedures using premium raw materials and advanced manufacturing processes. Every attenuator undergoes comprehensive electrical and mechanical testing to ensure consistent attenuation accuracy and dependable RF performance.
What is a TNC Attenuator?
A TNC Attenuator is a passive RF device that reduces RF or microwave signal power by a predetermined attenuation value while maintaining a constant 50 Ohm impedance. It protects sensitive RF equipment from excessive signal levels, minimizes signal reflections, and improves measurement accuracy in RF communication systems.
The TNC (Threaded Neill-Concelman) connector provides a secure threaded coupling mechanism that offers better vibration resistance and environmental reliability than bayonet-style connectors. TNC Attenuators are commonly used with Vector Network Analyzers (VNAs), spectrum analyzers, signal generators, RF amplifiers, wireless communication equipment, and microwave test systems.
