Norcross, GA (770) 455-0676,
This three-state attenuated switch is designed for frequencies from DC to 25 GHz. The three-state attenuated switch was designed to allow users to switch between three different states: through path (low loss), attenuated path (known high loss) and open state (with path for user to ground). The 3-State attenuated switch eliminates the use of external cables or attenuators maximizing RF characteristics and minimizing space and weight.
