It can be switched to a low loss state (less than 0.5 dB), attenuated state (20 dB across a broadband) or open state with one of the 2 RF inputs terminated into a 50 Ω termination. The CAS-37 tri-state attenuated coaxial switch is ideal for many applications including test & measurement where stringent signal fi delity switching, minimum device footprint, and switch reliability are of prime concern.
