RLC Electronics' VHF Switch Attenuator Model AS-120 is a "rocker switch" RF attenuator designed to operate over the frequency range from DC to 1.5 GHz. Attenuation from 1 to 101dB in 1 dB steps is provided by switching individually controlled attenuators connected in series. The total attenuation is the sum of those steps switched to the "in" position. These attenuators have excellent performance characteristics suitable for use in high reliability 50 ohm systems, and are highly repeatable. Attenuation can be easily seen by a quick glance at the rocker positions showing which attenuation values are in the circuit.
