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

(VCC = +2.7V to +5.5V, no RF signals applied, LO = open, IFOUT+ = IFOUT- = VCC, SHDN = high, LGND = GND = GNDLO = 0V,

TA = TMIN to TMAX. Typical values are at VCC = +3.0V and TA = +25°C, unless otherwise noted. Minimum and maximum values are

guaranteed by design and characterization over temperature.)

AC ELECTRICAL CHARACTERISTICS

(MAX2690 EV kit; VCC = +3.0V; PLO = -3dBm; PRF = -25dBm; SHDN = high; RFIN matched for 900MHz, 1.95GHz, and 2.45GHz as

noted below. Inductor connected from LGND to GND = 39nH for 900MHz operation, 27nH for 1.95GHz operation, and 6.8nH for

2.45GHz operation. TA = +25°C, unless otherwise noted.)
