Note 3: 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, unless otherwise noted.
Note 4: Min and max limits guaranteed by test at T A = +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.
