R573803445 is listed in the RF Switches range at ChipApex. The manufacturer field lists Radiall USA, Inc.. Its product description is SP4T RAMSES SMA2.9 40GHZ NORMALL. Review the specifications below when checking this part for your BOM.
The R573803445 is a general-purpose SP4T RF switch IC from the Ramses series by Radiall USA, Inc. It operates with SMA2.9 connectors and supports frequencies up to 40 GHz. The device utilizes a normally open configuration with positive common logic and requires a 28Vdc control voltage. It features TTL interface compatibility and includes D-sub connector integration for control signals.
Verify the specific Ramses series datasheet for detailed electrical parameters and pinout configurations before procurement. Confirm that the 28Vdc control voltage requirements align with the system power supply design. Ensure the SMA2.9 connector interface matches the existing board layout and mating components. Check for any environmental compliance certifications required for the intended application environment.
Select this component when a compact SP4T solution is needed for frequencies approaching 40 GHz. Consider the positive common logic requirement for control circuitry design. Evaluate the thermal management needs associated with the integrated D-sub connector interface. Compare against other Ramses series variants if different port counts or control voltages are preferred.
This part belongs to Radiall's Ramses series of high-performance RF switches. The series is designed for demanding applications requiring low insertion loss and high isolation. The R573803445 specifically addresses the need for multi-port switching in systems operating at millimeter-wave frequencies.
R573803645 is a documented parameter-equivalent alternative within the same Ramses series offering similar switching capabilities.
