FW-A Fixed Attenuators

Mini-Circuits FW-A Fixed Attenuators are attenuators with DC to 1200MHz frequency range and excellent flatness in attenuation. These attenuators feature 1dB to 20dB nominal attenuation, up to 1W rating, rugged unibody construction, precise performance, and excellent durability. The FW-A fixed attenuators support testing and measurement application and are suitable for ideal systems requiring precise attenuation across a wide frequency range. Typical applications include impedance matching and signal level adjustment.
