R573803640

Overview

The R573803640 is a general-purpose SP6T coaxial RF switch from the Ramses series, manufactured by Radiall USA, Inc. It operates within a frequency range of 0 Hz to 40 GHz and features a 50 Ohm impedance. The device utilizes an SMA2.9 connector interface and is designed for normally open operation with positive common configuration. It requires a 28 Vdc control voltage and supports TTL diode drive inputs. The component is RoHS3 compliant and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports ultra-wideband signal routing up to 40 GHz
• Provides single-pole six-throw switching capability
• Features normally open contact configuration for low insertion loss
• Compatible with standard TTL logic control interfaces

Applications

• Test and measurement instrumentation requiring high-frequency signal routing
• Wireless communication base station architectures
• Radar system signal distribution networks
• Electronic warfare equipment signal processing chains

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply conditions may vary. Confirm that the specific order suffix matches the required SMA2.9 connector variant and 28Vdc control specification. Ensure compliance with RoHS3 environmental standards is documented for your specific procurement requirements before finalizing orders.

Selection Notes

Select this component when designing systems requiring broad bandwidth coverage extending to 40 GHz. The SP6T topology allows flexible signal path management in complex RF layouts. Ensure the design accommodates the 28Vdc control voltage requirement and provides adequate thermal management for the specified operating temperature range. Verify mechanical fit for the SMA2.9 interface.

Part Context

This part belongs to the Ramses family of high-performance coaxial switches from Radiall. The series is engineered for demanding RF applications where signal integrity at millimeter-wave frequencies is critical. The R573803640 represents a specific configuration within this line, offering six output ports controlled by a single input.

Replacement Considerations

Cross-reference equivalent SP6T coaxial switches rated for 40 GHz operation. Verify compatibility of control voltages, specifically checking for 28Vdc versus other common levels like 12Vdc. Ensure mechanical interchangeability regarding the SMA2.9 connector type and mounting style.
