AC ELECTRICAL CHARACTERISTICS (continued)
MAX2395 EV kit, V CC = +2.7V to +3.3V, R BIAS = 12k ? , V VGC adjusted to obtain maximum rated output power, and T A = -40°C to
+85°C. I/Q inputs driven differentially with low- impedance source based on 3GPP UpLink reference measurement channel
(12.2kbps), envelope level 1V P-P . Typical values are at V CC = +2.85V and T A = +25°C, unless otherwise noted. See Tables 1 and 3 for
register settings.) (Note 2)

Guaranteed at T A = +25°C and T A = +85°C by production test, and guaranteed by design and characterization at T A = -40°C.
V DH is the high voltage applied to the shutdown pin.
Output power, linearity, noise power, and LO leakage specifications are met over this frequency range.
Specifications valid for all output power levels, unless limited by thermal noise at lower output power levels.
Guaranteed by design and characterization.
Tested at 1MHz and 2MHz in the passband.
