At T A = -40°C, the minimum and maximum values are guaranteed by design and characterization, unless otherwise noted.
At T A = -40°C and +105°C, the maximum value is guaranteed by design and characterization.
Measured using MAX12000 evaluation board with a DC-blocking capacitor at the input of LNA 1.
At T A = +25°C, the maximum value is guaranteed by design and characterization. Specification is corrected for board
losses on the MAX12000 EV kit.
Typical Operating Characteristics
