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 RF3700D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide
front-end selectivity in 372.00 MHz receivers. Receiver designs using this filter include superheterodyne with
10.7 MHz or 500 kHz IFs, direct conversion receivers and superregenerative receives. Typical applications
for these receivers are wireless remote control and security.
This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greater
than 40 dB, of the LO and image spurious responses in superheterodyne receivers with 10.7 MHz IFs. RFM’s
advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss
with simple external impedance matching.
