The DC-4 GHz, 1-60 dB, 2 Watt Bidirectional Attenuator is a precision RF component designed for controlled signal attenuation across a wide frequency range. With adjustable attenuation from 1 to 60 dB and 2 W power handling, it provides reliable signal-level management and excellent RF performance. Its bidirectional design allows signals to pass efficiently in either direction, making it suitable for versatile system configurations. Featuring a 2.2-5 interface, the SRFS-04XXZC2 is ideal for telecommunications, RF testing, laboratory equipment, wireless infrastructure, measurement systems, and other demanding RF applications requiring stable and accurate attenuation.
