AC ELECTRICAL CHARACTERISTICS (Modulator)

(MAX2021

Typical Application Circuit, VCC = 4.75V to 5.25V, GND = 0V, I/Q differential inputs driven from a 100Ω DC-coupled source,

0V common-mode input, PLO = 0dBm, 750MHz ≤ fLO ≤ 1200MHz, 50Ω LO and RF system impedance, R1 = 432Ω, R2 = 619Ω, R3 =

332Ω, TC = -40°C to +85°C. Typical values are at VCC = 5V, VBBI = 1.4VP-P differential, VBBQ = 1.4VP-P differential, fIQ = 1MHz, fLO =

900MHz, TC = +25°C, unless otherwise noted.) (Note 6)
