High-Gain Vector Multipliers
MAX2047 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 = 915MHz, input cur-
rent 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)
