The RF1172C is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to pro-

vide 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 wire-

less remote-control and security devices operating in Europe under ETSI I-ETS 300 220.

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.

Frequency aging is the change in fc with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above +65°C. Typ-

ically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.

The design, manufacturing process, and specifications of this device are subject to change.
