3 V, Low Current Operation plus Sleep Mode
Up to 10 mW Transmitter Power under FCC 15.247 Regulations
The TR8100 hybrid transceiver is ideal for short-range wireless data applications where robust
operation, small size, low power consumption and low cost are required. The TR8100 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 TR8100 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 re-
ceiver out-of-band rejection. The transmitter uses an internal “digital modulation” BPSK spread-
ing code, with data carried by either OOK or ASK modulation. The transmitter employs SAW
filtering to suppress output harmonics, facilitating compliance with FCC 15.247 regulations.
