Overview
The SF2460H is a Surface Acoustic Wave (SAW) bandpass filter designed for GPS applications. It operates at a center frequency of 1.25415 GHz with a bandwidth of 68.7 MHz, covering the range from 1.2198 GHz to 1.2885 GHz. The component features a 4-SMD, No Lead package and is rated for a DC voltage of 3 VDC. It supports an input power level of +10 dBm and functions within an operable temperature range of -40°C to +105°C.
Feature Summary
- Utilizes Surface Acoustic Wave technology for signal conditioning
- Engineered specifically for Global Positioning System reception
- Compact surface-mount design suitable for space-constrained electronics
Applications
- GPS receiver front-end filtering
- Satellite navigation systems
- Mobile device positioning modules
Procurement Notes
Verify the specific datasheet version before procurement, as specifications may vary by revision. Confirm that the 4-SMD No Lead package matches your PCB footprint requirements. Ensure the operating environment stays within the -40°C to +105°C temperature range to maintain performance integrity. Cross-reference the 1.25415 GHz center frequency with your system's local oscillator settings to guarantee proper signal acquisition.
Selection Notes
Select this component when a narrow-band SAW filter is required for L1 GPS frequencies. The 68.7 MHz bandwidth provides adequate passband coverage for standard GPS signals while rejecting out-of-band interference. Consider the 3V DC rating and +10 dBm input power limits when designing the RF front-end chain to prevent damage or distortion under high-signal conditions.
Part Context
