CAUTION! ESD SENSITIVE DEVICE
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
DC ELECTRICAL CHARACTERISTICS
(MAX2120 Evaluation Kit: V CC = +3.13V to +3.47V, V GC1 = +0.5V (max gain), T A = 0°C to +70°C. No input signals at RF, baseband
I/Os are open circuited, and LO frequency = 2150MHz. Default register settings except BBG[3:0] = 1011. Typical values measured
at V CC = +3.3V, T A = +25°C, unless otherwise noted.) (Note 1)
