RFM offers a full set of custom embedded wireless networking solutions like Zigbee wireless mesh sensor networks, RF modules, IC transceiver, IC transmitters and IC receivers. RFM, Inc. manufactures low power wireless and RF radio modules, wireless mesh nodes for distributed sensing on distributed sensor networks. Low Power radio, n../arrowband and short range devices, front end saw filters, active RFID, RFIC, coupled resonator filters, single silicon chips in the 70MHZ and 300-1000Mhz range.
The RF1181 is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed
to provide front-end selectivity in 916.5 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 wireless remote-control and security devices operating in the USA under FCC
Part 15 and in Canada under DoC RSS-210.
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). Quartz construction
provides excellent frequency stability over a wide temperature range.
RFM products are sold through a world-wide network of manufacturer's sales reps and distributors.
The purpose of this End-of-Life Product Notice is to communicate the obsolescence of the RF1181.
