Overview
The RSF-1582.400-31200-1411-TR is a Surface Acoustic Wave (SAW) filter designed for GPS RF applications, manufactured by Raltron Electronics. It operates at a center frequency of 1.5824 GHz with a bandwidth of 31.2 MHz. The component exhibits an insertion loss of 1.8 dB and maintains a nominal impedance of 50 Ohms. It utilizes a 5-pin surface mount device (SMD) package configuration suitable for automated assembly processes.
Feature Summary
- Surface Acoustic Wave technology optimized for GPS RF signal processing
- Center frequency alignment at 1.5824 GHz with 31.2 MHz bandwidth
- Standard 50 Ohm impedance matching for system integration
- Compact 5-pin surface mount device packaging
Applications
- GPS receiver front-end filtering
- RF signal conditioning in navigation modules
- Satellite positioning system components
Procurement Notes
Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics before integration. Ensure that the 5-pin SMD footprint matches the target PCB layout design. Confirm compliance requirements such as RoHS status directly from the manufacturer documentation to meet regulatory standards for the intended deployment environment.
Selection Notes
Select this component when a dedicated SAW filter is required for the 1.5824 GHz GPS band. The 31.2 MHz bandwidth defines the signal pass range. Consider the 1.8 dB insertion loss impact on overall system sensitivity. The 50 Ohm impedance must align with preceding and succeeding circuit stages to ensure proper signal transmission without reflection issues.
Part Context
This part belongs to the RSF series of SAW filters produced by Raltron Electronics. These components are engineered specifically for radio frequency applications requiring precise frequency selection. The model designation indicates specific center frequency and bandwidth parameters within the broader product family designed for global positioning systems.
Replacement Considerations
Direct substitutes require identical 1.5824 GHz center frequency, 31.2 MHz bandwidth, and 50 Ohm impedance. Verify physical pin compatibility for the 5-pin SMD package. Cross-reference insertion loss specifications to maintain system performance levels.
