The Narda 3202B-20 is a fixed coaxial attenuator delivering precise 20 dB signal reduction across DC to 18 GHz. Engineered for RF and microwave test systems, it maintains attenuation accuracy of ±0.5 dB while handling average input power to 2 Watts and peak pulse power to 500 Watts. The 50 Ohm, Type N connector design ensures low VSWR performance: 1.10:1 maximum from DC to 4 GHz, 1.20:1 to 12.4 GHz, and 1.35:1 to 18 GHz. Built for signal conditioning, receiver protection, and precision measurement applications.
