High-Dynamic-Range, Direct Up-/Downconversion
1500MHz to 2500MHz Quadrature Mod/Demod
Typical Operating Characteristics (continued)
(MAX2023 Typical Application Circuit, VCC = 4.75V to 5.25V, GND = 0V, I/Q differential inputs driven from a 100Ω DC-coupled source
(modulator), VBBI = VBBQ = 2.6VP-P differential (modulator), PRF = +6dBm (demodulator), I/Q differential output drives 50Ω differential load
(demodulator), 0V common-mode input/output, PLO = 0dBm, 1500MHz ≤ fLO ≤ 2300MHz, 50Ω LO and RF system impedance, R1 = 432Ω,
R2 = 562Ω, R3 = 301Ω, TC = -40°C to +85°C. Typical values are at VCC = 5V, fLO = 1850MHz, TC = +25°C, unless otherwise noted.)
