TO39-3 Case
Ideal Front-End Filter for Wireless Receiver in the UK and USA
Low-Loss, Coupled-Resonator Quartz Design
Simple External Impedance Matching
Rugged TO39 Hermetic Package
The RF1171 is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide
front-end selectivity in 418.0 MHz receivers. Receiver designs using this filter include superhet with
10.7 MHz direct conversion and superregen. Typical applications of these receivers are wireless remote-
control and security devices operating in the United Kingdom under DTI MPT 1340 and in the USA under
FCC Part 15.
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 ad-
vanced 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 frequency stabil-
ity over a wide temperature range.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1. Typical test circuit is shown for TO-39 RF filters.
2. Passband and reject bands are specified in reference to f
C
.
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-
band shape are dependent on the impedance matching component values and quality. Demonstration circuits are available for confirmation of device
performance.
5. One or more of the following U.S. Patents apply: 4,454,488; 4,616,197; and other pending.
6. All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale.
7. The design, manufacturing process, and specifications of this device are subject to change without notice.
8. The turnover temperature, T
