Description

The RF1172C is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 433.92 MHz receivers. Receiver designs using RF1172C  include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. Typical applications of RF1172C are wireless remote-control and security devices operating in Europe under ETSI I-ETS 300 220.

This coupled-resonator filter RF1172C (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 ofRF1172C is utilized to achieve high performance and very low loss with simple external impedance matching.
