The TR7002 hybrid transceiver is ideal for short-range wireless data applications where robust operation, small size, low power consumption and low cost are required. The TR7002 employs RFM’s 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 TR7002 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 FCC/ETSI I-ETS 300 220 and similar regulations

Developer Kits
The DR7002-DK kit allows for full demonstration or development of the third-generation (3G) TR7002 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 DR7002 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.

Kit Includes:
• 2x USB 2.0 Cables
• 2x 9V batteries
• VWO Configuration software
• 2x tuned, SMA antennas
• 2x DR development boards
• CD with documentation
