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

(Typical Operating Circuit as shown in Figure 1; VCC = 4.75V to 5.25V, TA = -40°C to +85°C, RBIAS = 280Ω, no RF inputs applied, RF

input and output ports are terminated with 50Ω. Typical values are at VCC = 5V and TA = +25°C, unless otherwise noted.)

AC ELECTRICAL CHARACTERISTICS

(Typical Operating Circuit as shown in Figure 1; VCC = 4.75V to 5.25V, TA = -40°C to +85°C, RBIAS = 280Ω, fIN = 2.14GHz

(MAX2045), fIN = 1.9GHz (MAX2046), fIN = 915MHz (MAX2047), input current range = 0 to 4mA (if using a current-mode DAC), and

differential input voltage range = 0 to 0.707V (if using a voltage-mode DAC). If using a current-mode DAC, voltage mode I/Q inputs

are left open. If using a voltage-mode DAC, all current-mode I/Q inputs are left open. Typical values are at VCC = 5V and TA =

+25°C, unless otherwise noted.) (Notes 1, 2, 3)
