Description

The RF1171D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 418.0 MHz receivers. Receiver designs using RF1171D include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. Typical applications of RF1171D are wireless remote-control and security devices operating in the USA under FCC Part 15.
 This coupled-resonator filter RF1171D (CRF) uses selective null placement to provide suppression, typically greater than 40 dB, of the LO and image spurious responses of superhet receivers with 10.7 MHz IF. RFM's advanced SAW design and fabrication technology of RF1171D is utilized to achieve high performance and very low loss with simple external impedance matching.
