3 GHz Rotary Attenuators

JFW offers a new family of rotary attenuators designed for applications with frequency ranges from DC to 3 GHz, and up to 3.6 GHz in one model. This family consists of dual concentric, bench top, and single rotary attenuators. They feature ranges of attenuation from 0 dB up to 110 dB in 1 dB or 10 dB increments, and have 50 Ohms impedance, and an input power average of 2 Watts.
