Overview
The R570452100LP is an SPDT coaxial switch from the Ramses series, designed for low PIM applications. It operates up to 18 GHz with a 50 Ohm impedance and SMA connectors. The device utilizes a latching mechanism with self-cut-off functionality, driven by a 12Vdc coil voltage and TTL diodes. Key electrical specifications include a VSWR of 1.4:1, insertion loss of 0.35 dB, and isolation of 60 dB. It features solder pin terminals and supports a mechanical life of 10 million cycles within a temperature range of -40°C to +85°C.
Feature Summary
- SPDT configuration with latching self-cut-off operation
- Low PIM design optimized for high-frequency signals
- Integrated TTL diode control interface
- SMA connector termination type
Applications
- Base station antenna switching systems
- Test and measurement instrumentation
- Wireless communication infrastructure
Procurement Notes
Verify component authenticity through authorized Radiall channels or certified distributors. Confirm that the specific suffix matches the required latching and low PIM specifications. Ensure compatibility with existing TTL drive circuits and 12Vdc power requirements before finalizing procurement orders.
Selection Notes
Select this model when low phase noise and minimal intermodulation distortion are critical for signal integrity at frequencies up to 18 GHz. The latching feature reduces continuous power consumption compared to non-latching variants. Verify that the SMA interface and solder pin mounting align with the target PCB layout and system constraints.
Part Context
This component belongs to the Ramses family of RF switches, which are engineered for demanding wireless environments. The Ramses series emphasizes performance stability and reliability in base station and test equipment applications where signal purity is paramount.
Replacement Considerations
Direct substitutes may include other Ramses series models with similar SPDT configurations and 18 GHz ratings. Verify that replacement parts match the 12Vdc latching requirement and low PIM characteristics to maintain system performance standards.
