MAX2900ETI+

MAX2900ETI+ is a complete single-chip 200mW transmitter. It is compliant with the FCC CFR47 part 15.247 902MHz to 928MHz ISM-band specifications. This transmitter IC offers 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 device is intended primarily for use with an external differential antenna. Applications include automatic meter readings, wireless security systems/alarms, wireless sensors, wireless data networks, and wireless building control.

• Modulation filter for direct sequence BPSK up to 8Mchips/s
