Quadrature Modulator/Demodulator

AC Electrical Characteristics (Modulator)

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

DC-coupled source, 0V common-mode input, PLO = 0dBm, fLO = 1900MHz to 2200MHz, 50Ω LO and RF system impedance, R1 =

432Ω, R2 = 562Ω, 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.) (Notes 6, 7)
