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

(MAX2837 evaluation kit: VCC_ = 2.7V to 3.6V, 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 50Ω, receiver baseband outputs are open;

90mVRMS differential I and Q signals applied to I, Q baseband inputs of transmitter in transmit mode, fREF = 40MHz, registers set to

recommended settings and corresponding test mode, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = 2.8V,

fLO = 2.5GHz, and TA = +25°C, unless otherwise noted.) (Note 1)
