SF2038B-2 Description

Short technical summary and product information.

The SF2038B-2 from RFMi is a Surface Acoustic Wave (SAW) filter specifically designed for use in Satellite Digital Audio Radio Service (SDARS) IF receiver systems. It operates with a nominal center frequency of 76.500 MHz, offering a typical insertion loss of 10.0 dB. The filter provides a 1dB passband bandwidth of 12.5 MHz, expanding to 18.0 MHz at 30dB attenuation, ensuring effective signal selectivity.

 

This component is housed in a compact 7.00mm x 5.00mm SMP-03 surface-mount case, making it suitable for space-constrained designs. It supports differential input and output with impedances of 175 ohms and 180 ohms, respectively. The operating temperature range is -40°C to +105°C, and it meets AEC-Q200 qualification standards, indicating its suitability for demanding automotive and industrial environments. The filter also complies with RoHS Directive 2002/95/EC.
