2 / 12 page SiGe High-Linearity, 1700MHz to 2200MHz Downconversion Mixer with LO Buffer/Switch 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS DC ELECTRICAL CHARACTERISTICS (MAX9994 Typical Application Circuit, VCC = +4.75V to +5.25V, no RF signal applied, IF+ and IF- outputs pulled up to VCC through inductive chokes, R1 = 806 Ω, R2 = 549Ω, TC = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +5V, TC = +25°C, unless otherwise noted.) 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.
