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-se-

quenced 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 sensi-

tive 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.
