Frequently Asked Questions

What is the center frequency and insertion loss specification of the SF2049E SAW filter?

SF2049E is centered at 915 MHz with a maximum insertion loss of 3.5 dB across its passband. The 50 Ohm input and output impedance allows direct connection in standard RF signal chains, making it suitable for ISM-band receive paths where low in-band loss is critical for sensitivity.

How does the SF2049E's SM3030-6 package footprint compare to common RF filter packages for board layout?

The SM3030-6 package measures 3.0 mm x 3.0 mm with a profile height of 1.38 mm, providing a compact SMD footprint that fits within tight RF module layouts. This is smaller than many ceramic bandpass filters, enabling designers to place the 915 MHz SAW filter close to the antenna port to minimize PCB trace losses.

Which wireless communication standards operating near 915 MHz can benefit from the SF2049E filter?

SF2049E is optimized for the 902–928 MHz ISM band covering protocols such as LoRa (at 915 MHz channel center), Sigfox (868–928 MHz region), IEEE 802.15.4g at 915 MHz, and passive UHF RFID systems. Its 3.5 dB insertion loss and 50 Ohm termination make it a direct-fit filter in these 915 MHz RF front-end designs.

Is tape-and-reel packaging available for SF2049E, and what are the implications for high-volume SMT assembly?

Yes, SF2049E is supplied in tape-and-reel format, enabling automated SMT pick-and-place at production line speeds typically exceeding 5,000 placements per hour. The 6-pin SM3030-6 reflow-solderable package is compatible with standard SAC305 lead-free solder profiles with a peak reflow temperature of 260°C.
