The SF2049E is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for operation in the 915 MHz ISM band. This component offers a center frequency of 915.00 MHz with a nominal insertion loss of 2.2 dB within the 902 to 928 MHz band. It has a bandwidth of 26 MHz and a VSWR of 1.6 to 2.3 in the specified band.
The filter is housed in a compact 6-SMD, No Lead package with a nominal footprint of 3.0 x 3.0 mm, making it suitable for surface mounting. The operating temperature range is -40 to +85 °C, and it is suitable for lead-free soldering with a maximum soldering profile of 260°C for 30 seconds. The device complies with Directive 2002/95/EC (RoHS).
Key electrical characteristics include a source and load impedance of 50 Ω, a maximum input power level of 15 dBm, and a maximum DC voltage of 5 V on any non-ground terminal. The attenuation specifications show significant roll-off outside the passband, with values such as 50 dB at DC to 800 MHz and 32 dB at 960 to 1080 MHz.
This SAW filter is designed for applications requiring selective filtering around the 915 MHz frequency, commonly found in ISM band communication systems.
