Note A: Maximum reliable continuous power applied to the baseband differential port is +20dBm from an external 100Ω source.

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

(MAX2021 Typical Application Circuit, VCC = +4.75V to +5.25V, GND = 0V, I/Q inputs terminated into 100Ω differential, LO input terminat-

ed into 50Ω, RF output terminated into 50Ω, 0V common-mode input, R1 = 432Ω, R2 = 619Ω, R3 = 332Ω, TC = -40°C to +85°C, unless

otherwise noted. Typical values are at VCC = +5V, VBBI = VBBQ = 1.4VP-P, fIQ = 1MHz, TC = +25°C, unless otherwise noted.) (Notes 1, 2)
