R573403510

Overview

The Radiall R573403510 is a Ramses series coaxial switch featuring an SP5T topology with SMA connectors. It operates at frequencies up to 18 GHz and utilizes a normally open configuration. The device requires a 28 Vdc positive common control signal for actuation. Key electrical specifications include a minimum isolation of 60 dB and a maximum insertion loss of 0.5 dB, measured at the test frequency of 18 GHz. The component maintains a characteristic impedance of 50 Ohms throughout its operational range.

Feature Summary
