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 RF3171D 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
or 500 kHz IF, direct conversion and superregen. Typical applications of these receivers are wireless remotecontrol
and security devices operating 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
advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss
with simple external impedance matching.
