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 TR1004 hybrid transceiver is ideal for short-range wireless data applications where robust operation,
small size, low power consumption and low cost are required. The TR1004 employs RFM’s amplifiersequenced
hybrid (ASH) architecture to achieve this unique blend of character- istics. All critical RF functions
are contained in the hybrid, simplifying and speeding design-in. The receiver section of the TR1004 is
sensitive and stable. A wide dynamic range log detector, in combination with digital AGC and a compound
data slicer, provide robust performance in the presence of on-channel interference or noise. Two stages of
SAW filtering provide excellent receiver out-of-band rejection. The transmitter includes provisions for both onoff
keyed (OOK) and amplitude-shift keyed (ASK) modulation. The transmitter employs SAW filtering to
suppress output harmonics, facilitating compliance with FCC 15.249 and similar regulations.
