High-Dynamic-Range, Direct Up-/Downconversion

1500MHz to 2300MHz Quadrature Mod/Demod

AC ELECTRICAL CHARACTERISTICS (Modulator) (continued)

(MAX2023 Typical Application Circuit, when operated as a modulator, VCC = +4.75V to +5.25V, GND = 0V, I/Q differential inputs

driven from a 100Ω DC-coupled source, 0V common-mode input, 50Ω LO and RF system impedance, R1 = 432Ω, R2 = 562Ω,

R3 = 300Ω, TC = -40°C to +85°C. Typical values are at VCC = +5V, VBBI = VBBQ = 2.66VP-P differential, fIQ = 1MHz, PLO = 0dBm,

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