MAX2021
High-Dynamic-Range, Direct Up-/Downconversion
650MHz to 1200MHz Quadrature Mod/Demod
Typical Operating Characteristics
(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.)
