200mW Single-Chip Transmitter ICs for
868MHz/915MHz ISM Bands
ABSOLUTE MAXIMUM RATINGS
VCC to GND ...........................................................-0.3V to +5.0V
Analog/Digital Input Voltage to GND..........-0.3V to (VCC + 0.3V)
Analog/Digital Input Current ..............................................±10µA
Continuous Power Dissipation (TA = +70°C)
28-Pin QFN-EP (derate 28.5mW/°C above +70°C)............2W
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature .....................................................+150°C
Storage Temperature Range .............................-65°C to +150°C
Lead Temperature (soldering, 10s) .................................+300°C
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.
CAUTION! ESD SENSITIVE DEVICE
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.
Part Selection Information
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.

DC ELECTRICAL CHARACTERISTICS
(VCC = +2.7V to +4.5V, EN = OOKIN = REFEN = high, TA = -40°C to +85°C. Typical values are at VCC = +4.5V, TA = +25°C, unless
otherwise noted.) (Note 1)
