The RF3446E is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 433.92 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 operating in Europe under ETSI I-ETS 300 220.

Applications Characteristics For the Receivers within Internet of Things and M2M wireless remote control and security devices: | - Operating under ETSI-ETS 300 220 | - That require rejection of strong out-of-band signals (needing, for example, typical out-of-band rejection of 50 dB); | - That may require special rejection at -10.7MHz for local oscillator rejection and special rejection at -21.4MHz for image spurious response for typical superhet receivers.
