Overview
The R573F22425 is a single-pole four-throw (SP4T) radio frequency switch manufactured by Radiall USA, Inc. under the RAMSES series. It operates within a frequency range of DC to 26.5 GHz and maintains a 50 Ohm impedance. The device utilizes latching technology with a 12Vdc TTL control signal and features a D-sub connector interface. Key electrical specifications include a maximum insertion loss of 0.5 dB and minimum isolation of 60 dB. It functions reliably across an operating temperature range of -40°C to 85°C.
Feature Summary
- SP4T configuration for RF signal routing
- Latching mechanism controlled by 12Vdc TTL signals
- High isolation performance up to 60 dB
- D-sub connector interface for control integration
Applications
- Test and measurement instrumentation
- Wireless communication base stations
- Aerospace and defense radar systems
- Satellite ground station equipment
Procurement Notes
Verify the specific D-sub connector pinout and mating cable requirements before procurement. Confirm that the 12Vdc TTL control voltage aligns with the system's power supply architecture. Ensure the SMA interface compatibility matches the existing RF chain components. Check for any specific environmental certifications required for the intended deployment location.
Selection Notes
Select this component when high-frequency operation up to 26.5 GHz is required alongside latching functionality. Compare insertion loss and isolation metrics against alternative SP4T switches to ensure signal integrity. Consider the physical footprint of the D-sub connector for panel mounting constraints. Evaluate thermal management needs given the -40°C to 85°C operating range.
Part Context
This part belongs to the RAMSES series of coaxial switches designed for demanding RF applications. It complements other Radiall interconnect solutions by providing reliable signal switching in compact modules. The series is engineered for durability in harsh environments, supporting both commercial and industrial sectors requiring precise RF path management.
Replacement Considerations
Consult official Radiall documentation for direct cross-reference equivalents. Verify that substitute parts match the 26.5 GHz frequency limit and 50 Ohm impedance. Ensure replacement units support identical 12Vdc TTL latching controls and D-sub interfaces.
