RF1210B

The RF1210B is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 303.825 MHz receivers. Receiver designs using RF1210B include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. Typical applications of RF1210B are wireless remote-control and security devices operating in the USA under FCC Part 15, Australia, Japan and Korea.

This coupled-resonator filter (CRF) RF1210B 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 ofRF1210B is utilized to achieve high performance and very low loss with simple external impedance matching (not included). Quartz construction provides excellent frequency stability over a wide temperature range. Our new patent pending solder seal process utilizes a Faraday shield lid, which improves out of band rejection.
