SF2315E-1

Overview

The RFMi SF2315E-1 is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a center frequency of 782 MHz with a bandwidth of 29 MHz, covering a range from 777 MHz to 787 MHz. The component features an impedance of 50 ohms and a maximum insertion loss of 2.6 dB. It is housed in an SM-3030-6 package with SMD/SMT termination types. The device supports operating temperatures between -40°C and +85°C and is available in reel, cut tape, and MouserReel packaging formats.

Procurement Notes

Verify current availability status as the component may be discontinued or subject to shipping restrictions in certain regions. Confirm RoHS compliance details directly with the manufacturer or authorized distributors before procurement. Ensure packaging format requirements match specific production needs, such as reel or cut tape options.

Selection Notes

Select this component for applications requiring a 782 MHz center frequency with a 29 MHz bandwidth. Consider the 50-ohm impedance matching and 2.6 dB insertion loss characteristics for system integration. Evaluate the SM-3030-6 package dimensions against PCB layout constraints and verify temperature range compatibility with the operational environment.

Part Context

This SAW filter belongs to the RFMi general-purpose RF filter series. It is distinct from similar models like the SF2315E, which offers a narrower 10 MHz bandwidth and lower insertion loss of 2.2 dB. The SF2315E-1 provides a wider bandwidth option for broader signal coverage within the 777-787 MHz range.

Replacement Considerations

The SF2315E is a related variant but differs in bandwidth (10 MHz vs 29 MHz) and insertion loss (2.2 dB vs 2.6 dB). Substitution requires verification that the narrower bandwidth of the SF2315E meets the system's spectral requirements. No other direct substitutes are confirmed in public documentation.
