Description

This is a high-power fixed RF attenuator designed to reduce signal strength by 40 decibels (dB)—cutting the signal power to 1/10,000th of its original level—across a frequency range of DC to 4 GHz. With a 100 Watt power rating, it’s ideal for demanding RF environments such as transmitter testing, radar systems, and high-power communication setups. 📐 Key Specifications - Attenuation: 40 dB (99.99% power reduction) - Power Handling: 100 Watts continuous wave (CW) - Frequency Range: DC to 4 GHz - Connector Type: N-type, male-to-female - Impedance: 50 ohms - VSWR: Typically ≤ 1.25:1 (some models as low as 1.20:1) - Return Loss: Better than 20 dB - Construction: - Body: Stainless steel or anodized aluminum - Contacts: Gold-plated BeCu - Cooling: Integrated heatsink for passive thermal dissipation - Operating Temp: Commonly -55°C to +125°C 🧰 Applications - High-Power RF Testing: Protects analyzers and receivers from overload - Signal Isolation: Reduces interference and crosstalk in dense RF environments - Impedance Matching: Maintains system balance in complex RF chains - Radar, Defense & Broadcast: Ideal for systems requiring precise, high-power signal control 📦 Real-World Examples - Centric RF C4N100-40M: 100W, 40 dB, 4 GHz attenuator with stainless steel N connectors - Mini-Circuits BW-40N100W+: Bi-directional, 100W, 40 dB attenuator with excellent VSWR - SSB BW-40N100W+: Designed for measurement and transmitter technology, usable up to 5 GHz
