The RF1302 is a low-loss, compact and economical surface-acoustic-wave (SAW) filter designed to provide

front-end selectivity in 439.250 MHz receivers. Typical applications of these FSK receivers are wireless

remote-control and security devices operating in Europe.

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). Quartz construction provides excellent frequen-

cy stability over a wide temperature range.

1. Typical test circuit is shown for TO-39 RF filters.

2. Passband and reject bands are specified in reference to f

3. All characteristics are specified over the operating temperature range and typical aging for 10 years.

4. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture. Note that insertion loss, bandwidth, and pass-
