SF2236E

Overview

The SF2236E is a surface acoustic wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 1.6425 GHz with a bandwidth of 35 MHz, covering a range from 1.625 to 1.66 GHz. The component features an insertion loss of 1.8 dB and is designed for a 50 Ohm impedance system. It has a voltage rating of 3 V and supports SMD/SMT board mounting in an SM-3030-6 package. The device functions within a temperature range of -20°C to +75°C.

Feature Summary

• Surface acoustic wave technology for signal conditioning
• Bandpass filtering capability centered at 1.6425 GHz
• Compact surface mount design for board integration

Applications

• General purpose RF applications requiring SAW filtering
• Wireless communication systems operating in the specified frequency range

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status prior to procurement. Ensure storage conditions align with specified temperature limits. Validate package integrity upon receipt to prevent damage to the sensitive surface acoustic wave structure during handling and installation processes.

Selection Notes

Select this component when a narrow bandpass filter is required around 1.6425 GHz. Consider the 35 MHz bandwidth and 1.8 dB insertion loss against system performance needs. Ensure the SM-3030-6 package fits the available PCB space. Verify that the 3 V voltage rating and operating temperature range meet the environmental constraints of the target application design.
