SAW Filter

The RF3336C is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide
front-end selectivity in 868.35 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 arewireless remote-control and security devices operating in Europe under ETSI I-ETS 300 220, in Germany
under FTZ 17 TR 2100, in the United Kingdom under DTI MPT 1340 (for automotive only), in France under
PTT Specifications ST/PAA/TPA/AGH/1542, and in Scandinavia.
This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greaterthan 30 dB, of the LO and image spurious responses of superhet receivers with 10.7 MHz IF. RFMi'sadvanced SAW design and fabrication technology is utilized to achieve high performance and very low loss
with simple external impedance matching.
