Downconversion 1500MHz to 3000MHz
Quadrature Modulator/Demodulator
Typical Operating Characteristics (continued)
(MAX2022 Typical Application Circuit, 50Ω LO input, R1 = 432Ω, R2 = 562Ω, R3 = 301Ω, VCC = 5V, PLO = 0dBm, fLO = 2140MHz,
VI = VQ = 109mVP-P differential, fIQ = 1MHz, I/Q differential inputs driven from a 100Ω differential DC-coupled source, common-mode
input from 0V, TC = +25°C, unless otherwise noted.)
