ABSOLUTE MAXIMUM RATINGS

DC ELECTRICAL CHARACTERISTICS

otherwise noted.) (Note 1)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

Five different versions are available. The versions differ

by their frequency band of operation, and by the synthe-

sizer’s mode of operation. The MAX2900 has an internal

8-channel synthesizer.

The MAX2901 and MAX2903 are dual-channel versions

with a selectable internal synthesizer division ratio of 62

or 63. The MAX2901 operates in the 902MHz to

928MHz ISM band and the MAX2903 operates in the

867MHz to 870MHz European ISM band.

The MAX2902 and MAX2904 require an off-chip fre-

quency synthesizer. The MAX2902 operates in the

902MHz– 928MHz ISM band and MAX2904 operates in

the 867MHz–870MHz European ISM band.

The MAX2901–MAX2904 provide LO outputs to drive a

receiver and/or an external synthesizer.
