SF2385H

Overview

The SF2385H is a Surface Acoustic Wave (SAW) band-pass filter designed for GPS applications. It operates at a center frequency of 1587.5 MHz with a bandwidth of 57 MHz. The device features an insertion loss ranging from 2.0 to 2.5 dB within the 1559 to 1616 MHz range. It utilizes a 50 Ohm impedance and is housed in an SM2016-4 SMD/SMT package. The component supports operation down to -45°C.

Feature Summary

• Surface Acoustic Wave technology for signal conditioning
• Optimized for GPS frequency bands
• Compact surface-mount packaging

Applications

• GPS receiver front-end filtering
• Global navigation satellite systems
• Wireless communication modules requiring 1.5 GHz band isolation

Procurement Notes

Verify the specific datasheet version from RFMi or authorized distributors to confirm RoHS compliance status and exact mechanical dimensions. Ensure the SM2016-4 package footprint matches your PCB design requirements. Cross-reference the center frequency and bandwidth specifications against your system's operational standards before finalizing procurement decisions.

Selection Notes

Select this component when a compact SAW filter is required for GPS signals around 1587.5 MHz. Consider the 2.5 dB maximum insertion loss and 57 MHz bandwidth constraints. The SM2016-4 package suits space-constrained designs. Verify temperature stability if operating below -45°C is not required.
