AC ELECTRICAL CHARACTERISTICS—MAX9989

(Typical Application Circuit, V

= 4.75V to 5.25V, 50Ω environment, +4dBm < P < +10dBm, 700MHz < f < 1100MHz,

IN IN

= 5.0V, P = +7dBm, f = 900MHz, and

= -40°C to +85°C, unless otherwise noted. Typical specifications are for V

= +25°C, unless otherwise noted.) (Note 1)

Note 1: Devices are 100% DC screened and AC production tested for functionality. Data sheet typical specifications are derived

from the average of 30 units from a typical lot, and are tested under the conditions specified for the typical specifications.

Note 2: DC current limits at -40°C are guaranteed by design and characterization.
