The Weinschel 57 is a fixed coaxial attenuator engineered for precision RF and microwave signal control from DC to 6.0 GHz. This 50 Ω impedance device delivers attenuation values from 3 dB to 40 dB with excellent VSWR performance and minimal signal distortion across its operating bandwidth. The Model 57 handles up to 150 Watts average power (derated to 15 Watts at 125°C) and 10 kilowatts peak power, making it suitable for both continuous and pulsed RF applications.
