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 DR7000-EV hybrid transceiver module is ideal for short-range wireless data applications
where robust operation, small size, low power consumption and low cost are required. The
DR7000-EVDR7000-EV utilizes RFM’s TR7000 amplifier-sequenced hybrid (ASH) architecture to
achieve this unique blend of characteristics. All critical RF functions are contained in the hybrid,
simplifying and speeding design-in. The receiver section of the DR7000-EV 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 on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The transmitter
employs SAW filtering to suppress output harmonics, facilitating compliance with ETSI I-ETS 300
220 and similar regulations.
The DR7000-DK kit allows for full demonstration or development of the third-generation (3G) TR7000 Virtual Wire
device. The kit provides “Out of the box” operation with or without the accompanying software. 2-way Range Test
capability is included by simply snapping on the included 9V battery, turn on power, and configuring the opposite
board for transmit. A small area is available for custom development with other popular microprocessors. The
DR7000 Data Radio boards are configured to operate at a data rate of 4.8 kbps. The kits are shipped with a pair of
data radio boards and matching antennas. Data Radio boards with antennas can be purchased separately for
development of applications.
