447.7 MHz SAW Filter

The RF1408D is a low-loss, compact, and economical surface-acoustic-wave (SAW) Filter designed to provide front-end selectivity in 447.7 MHz receivers. Receiver designs using this Filter include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. Typical applications of these receivers are Wireless remote- control and security devices (especially for automotive keyless entry) operating in the USA under FCC Part 15, in Canada under RSS-210, and in Italy This coupled-resonator Filter (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. RFMs advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching. Pb By RF Monolithics, Inc.
