SF2161E

Overview

The SF2161E is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for signal conditioning in the 2.65 GHz frequency range. It features a center frequency of 2.65 GHz with a bandwidth of 70 MHz and an insertion loss of 2 dB. The component operates at 3 V and maintains a 50 Ohm impedance. It is housed in an SM3030 package, measuring 3.00mm x 3.00mm, and is available in Tape & Reel packaging.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• Optimized for 2.65 GHz general purpose RF applications
• Compact SM3030 surface mount package design

Applications

• General purpose RF signal conditioning
• Wireless communication systems operating near 2.65 GHz
• Mobile device front-end modules

Procurement Notes

Verify the specific datasheet version from RFMi or authorized distributors to confirm exact electrical tolerances and RoHS compliance status. Ensure the SM3030 package dimensions match your PCB footprint requirements. Confirm availability through official channels as inventory levels fluctuate.

Selection Notes

Select this component when a SAW filter is required for the 2.65 GHz band with low insertion loss. The 70 MHz bandwidth suits applications needing moderate selectivity. Consider the 3 V operating voltage and 50 Ohm system impedance compatibility before integration into the circuit design.

Part Context
