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.
CAUTION! ESD SENSITIVE DEVICE
DC ELECTRICAL CHARACTERISTICS TABLE
(MAX2839 Evaluation Kit, V CC _ = 2.7V to 3.6V, T A = -40°C to +85°C, Rx set to the maximum gain. RXTX set according to operating
mode, ENABLE = CS = high, SCLK = DIN = low, no input signal at RF inputs, all RF inputs and outputs terminated into 50 Ω .
90mV RMS differential I and Q signals (1MHz) applied to I, Q baseband inputs of transmitter in transmit mode, all registers set to rec-
ommended settings and corresponding test mode, unless otherwise noted. Typical values are at V CC_ = 2.8V, f LO = 2.5GHz and
T A = +25°C, unless otherwise noted.) (Note 1)
