General Description
The MAX2900–MAX2904 complete single-chip 200mW
transmitters are designed for use in the 868MHz/
915MHz frequency bands. The MAX2900/MAX2901/
MAX2902 are compliant with the FCC CFR47 part 15.247
902MHz to 928MHz ISM-band specifications. MAX2903/
MAX2904 are compliant with the ETSI EN330-220 speci-
fication for the European 868MHz ISM band.
These transmitter ICs offer a high level of integration
while minimizing the number of external components.
This is achieved by full integration of the transmit modu-
lator, power amplifier, RF VCO, 8-channel frequency syn-
thesizer, and baseband PN sequence lowpass filter. By
filtering the BPSK modulation, the spurious emissions are
reduced, enabling up to eight independent transmit
channels in the U.S. ISM band. Inputs are provided for
spread-spectrum BPSK, ASK, and OOK. FM can be
achieved by directly modulating the VCO. The devices
are intended primarily for use with an external differential
antenna.
