AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2687/MAX2689/MAX2694 EV kit, VCC = 1.6V to 3.6V, TA = -40NC to +85NC, fRFIN = 1575.42MHz. Typical values are at VCC =

2.85V and TA = +25NC, unless otherwise noted.) (Note 3)

Note 3: Min and max limits guaranteed by test at TA = +25°C and guaranteed by design and characterization at TA = -40°C and

TA = +85°C, unless otherwise noted.

Note 4: Min and max limits guaranteed by test at TA = +25°C.

Note 5: Min limit guaranteed by design and characterization.

Note 6: Measured with the two tones located at 1MHz and 2MHz offset from the center of the GPS band with -27dBm/tone for the

MAX2687, -30dBm/tone for the MAX2689, and -24dBm/tone for the MAX2694.

Note 7: Measured with input tones at 1713MHz (-27dBm) and 1851MHz (-39dBm).

Note 8: Measured with a tone located at the center of the GPS band.
