The RF1336B is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to pro-

vide 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 are wire-

less 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 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 is utilized to achieve high performance and very low loss

with simple external impedance matching (not included). Our new patent pending solder seal process uti-

lizes a Faraday shield lid, which improves out of band rejection.
