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

(MAX2830 EV kit, VCC_ = 2.7V to 3.6V, VCCPA = VCCTXPA = 2.7V to 4.2V, TA = -40°C to +85°C, Rx set to the maximum gain. CS =

high, RXHP = SCLK = DIN = ANTSEL = low, RSSI and clock output buffer are off, no signal at RF inputs, all RF inputs and outputs

terminated into 50Ω, receiver baseband outputs are open. 100mVRMS differential I and Q signals (54Mbps IEEE 802.11g OFDM)

applied to I/Q baseband inputs of transmitter in transmit mode, fREF = 40MHz, and registers set to recommended settings and corre-

sponding test mode, unless otherwise noted. Typical values are at VCC = 2.8V, VCCPA = 3.3V, and TA = +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)
