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.
