SF2038B Description

Short technical summary and product information.

The SF2038B is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, operating at a center frequency of 76.5 MHz. This component is specifically designed for use in SDARS (Satellite Digital Audio Radio Service) receivers, offering a typical insertion loss of 10dB and a 1dB bandwidth of 12.5 MHz to 14.0 MHz.

 

The filter is housed in a compact 10-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and a maximum height of 2.00mm, making it suitable for surface mounting. It operates within a temperature range of -40°C to +85°C and features differential input and output impedances of 175 ohms and 180 ohms, respectively.

 

Key electrical characteristics include a typical amplitude ripple of 0.70 dB over ±6.25 MHz and a group delay variation of 40 ns over the same frequency range. The rejection specifications are detailed across various frequency bands, ensuring signal integrity in its intended application. The device also complies with RoHS3 directives and has a Moisture Sensitivity Level of 1.
