SBF1G57542S473

Overview

The SBF1G57542S473 is a Surface Acoustic Wave (SAW) filter manufactured by NextGen Components. It operates at a center frequency of 1.57542 GHz with a bandwidth of 32.64 MHz. The component features low insertion loss of 1 dB and utilizes a 6-pad configuration in a 3838 surface-mount package measuring 3.8 mm x 3.8 mm x 1.50 mm. Designed for high performance, it offers low amplitude ripple and sharp rejection characteristics in both out-of-band regions.

Feature Summary

• Low-loss SAW technology
• Low amplitude ripple
• Sharp out-of-band rejection

Applications

• Wireless communication systems
• GPS receiver front-ends
• Satellite navigation modules

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as tape and reel specifications may vary. Confirm that the 3838 package dimensions align with your PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles for 6-pad surface mount components. Cross-reference the center frequency against your system design specifications to guarantee operational accuracy.

Selection Notes

Select this component when a compact SAW filter is required for L-band applications near 1.575 GHz. The 3838 package size suits space-constrained designs. Consider the 1 dB insertion loss for link budget calculations. Verify that the 32.64 MHz bandwidth meets the signal processing needs of the target application without excessive attenuation.
