TR3003 - 4/4/08

• Designed for Short-Range Wireless Data Communications

• Supports RF Data Transmission Rates Up to 115.2 kbps

• 3 V, Low Current Operation plus Sleep Mode

• Stable, Easy to Use, Low External Parts Count

• Complies with Directive 2002/95/EC (RoHS)

The TR3003 hybrid transceiver is ideal for short-range wireless data applications where robust operation,

small size, low power consumption and low cost are required. The TR3003 employs RFM’s amplifier-

sequenced 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 TR3003 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 Part 15 and similar regulations.
