Overview

  • Versions for U.S. 902MHz to 928MHz Band and European 868MHz Band
  • -7dBm to +23dBm Adjustable Differential RF Output Power
  • +23dBm Output Power at 4.5V, +20dBm Output Power at 3.0V
  • Support BPSK, OOK, ASK, and FM Modulations
  • Modulation Filter for Direct Sequence BPSK up to 8Mchips/s
  • Fully Integrated VCO with On-Chip Tank
  • Extremely Low Frequency Pulling for OOK Modulation (typ 60kHz peak, 5kHz RMS)
  • Integrated Frequency Synthesizer for up to 8 Channels (MAX2900)
  • +2.7V to +4.5V Supply Operation
  • Small 28-Pin QFN Package with Exposed Pad (5mm x 5mm)

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.
