• Complies with Directive 2002/95/EC (RoHS)
The TR3002 hybrid transceiver is ideal for short-range wireless data applications where robust operation,
small size, low power consumption and low cost are required. The TR3002 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 TR3002 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.
