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
(MAX2831 EV kit: V CC_ = 2.7V to 3.6V, V CCPA = V CCTXPA = 2.7V to 4.2V, T A = -40°C to +85°C, Rx set to the maximum gain. CS =
high, RXHP = SCLK = DIN = low, RSSI and clock output buffer are off, no signal at RF inputs, all RF inputs and outputs terminated
into 50 ? , receiver baseband outputs are open. 100mV RMS differential I and Q signals (54Mbps IEEE 802.11g OFDM) applied to I/Q
baseband inputs of transmitter in transmit mode, f REF = 40MHz, and registers set to recommended settings and corresponding test
mode, unless otherwise noted. Typical values are at V CC = 2.8V, V CCPA = 3.3V, and T A = +25°C, LO frequency = 2.437GHz, unless
otherwise noted. RF inputs/outputs specifications are referenced to device pins and do not include 1dB loss from EV kit PCB, balun,
and SMA connectors.) (Note 1)
