SMP Attenuator
SMP Attenuators are compact, high-performance RF and microwave components designed to reduce signal power while maintaining excellent impedance matching and signal integrity. Featuring a push-on (blind-mate) SMP interface, these attenuators are ideal for high-density RF assemblies where space is limited and fast, reliable connections are required. Supporting frequencies up to 40 GHz, SMP Attenuators are widely used in aerospace, defense, satellite communication, radar systems, electronic warfare, RF test equipment, and high-speed communication systems.
At SRFS Teleinfra, we manufacture precision SMP Attenuators using premium RF resistor technology, high-quality SMP connectors, and advanced CNC machining processes. Our attenuators deliver low VSWR, excellent return loss, accurate attenuation values, and superior electrical performance for demanding microwave applications.
Every SMP Attenuator is manufactured in India under strict quality control procedures and undergoes comprehensive electrical and mechanical testing to ensure dependable RF performance, long service life, and consistent attenuation accuracy.
What are SMP Attenuators?
An SMP Attenuator is a passive RF component that reduces the amplitude of an RF or microwave signal by a fixed attenuation value while maintaining a constant 50 Ohm impedance. It protects sensitive RF equipment from excessive signal power, minimizes reflections, and improves measurement accuracy.
The SMP (SubMiniature Push-on) connector features a compact blind-mate interface capable of broadband operation up to 40 GHz, making it ideal for densely packed electronic assemblies and modular microwave systems.
