ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(MAX2659 EV kit; V
CC
= 1.6V to 3.3V, T
A
= -40°C to +85°C, no RF signals are applied. Typical values are at V
CC
= 2.85V and
T
A
= +25°C, unless 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.
Note 1: Min and Max limits guaranteed by test at T
A
= +25°C and guaranteed by design and characterization at T
A
= -40°C and
T
A
= +85°C.
Note 2: Guaranteed by design and characterization.
Note 3: Measured with the two tones located at 5MHz and 10MHz offset from the center of the GPS band with -40dBm/tone.
Note 4: Measured with a tone located at 5MHz offset from the center of the GPS band.
