SF2204E-1

Overview

The SF2204E-1 is a general-purpose RF Surface Acoustic Wave (SAW) filter manufactured by RFMi. It operates at a center frequency of 1.9 GHz with a bandwidth of 40 MHz, covering the range from 1880 to 1920 MHz. The component features an insertion loss of 1.8 dB and is designed for 50 Ohm impedance systems. It is housed in a compact SM-3030-6 package with six SMD no-lead terminals, suitable for surface-mount assembly.

Feature Summary

• Utilizes Surface Acoustic Wave technology for signal conditioning
• Optimized for 1.9 GHz general-purpose RF applications
• Compact SM-3030-6 surface-mount package design

Applications

• Wireless communication modules
• RF signal filtering in mobile devices
• General-purpose radio frequency circuits

Procurement Notes

Verify the specific ordering suffix to ensure the correct insertion loss variant, as the standard SF2204E differs from the SF2204E-1. Confirm the package type matches the required PCB footprint. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the supplier provides official datasheets for technical validation before procurement.

Selection Notes

Select this component when a 1.9 GHz SAW filter with low insertion loss is required. Compare the 1.8 dB loss against the standard SF2204E's 2.7 dB loss to determine suitability for power-sensitive designs. Ensure the 40 MHz bandwidth aligns with the system's channel requirements. Verify compatibility with the target impedance and mounting constraints.

Part Context

RFMi, now part of Akoustis Technologies, specializes in RF components using SAW, crystal, and ceramic technologies. The SF2204E-1 belongs to their SAW filter lineup, designed for digital and wireless applications. This series supports various frequency bands and offers solutions for signal integrity in modern electronic devices.

Replacement Considerations

The SF2204E is a related model but exhibits higher insertion loss (2.7 dB vs. 1.8 dB). Substitution requires verification that the increased loss is acceptable within the system's link budget. No other direct substitutes are confirmed in public documentation.
