AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2022 Typical Application Circuit, VCC = +4.75V to +5.25V, GND = 0V, I/Q differential inputs driven from a 100

Ω DC-coupled

source, 0V common-mode input, PLO = 0dBm, 1900MHz

≤ fLO ≤ 2200MHz, 50Ω LO and RF system impedance, R1 = 432Ω, R2 =

562

Ω, R3 = 301Ω, TC = -40°C to +85°C. Typical values are at VCC = +5V, VBBI = 109mVP-P differential, VBBQ = 109mVP-P differential,

fIQ = 1MHz, TC = +25°C, unless otherwise noted.) (Note 1)
