MAX2900ETI+ by Analog Devices

200mW Single-Chip Transmitter ICs for 868MHz/915MHz ISM Bands


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 specification 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 modulator, power amplifier, RF VCO, 8-channel frequency synthesizer, 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.
