W-CDMA Upconverter and PA Driver
with Power Control
AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2383 EV Kit; VCC = +2.7V to +3.0V; SHDN = LO_EN = +1.5V; IF source impedance = 400Ω (differential), IF input level =
-16dBm (differential); LO input level = -10dBm, differential LO drive from 150Ω source impedance; mixer upconverter and PA driver
are cascaded directly through an interstage matching network; DROUT drives a 50Ω load impedance; VGC = 2.0V; fIF = 380MHz,
fRF = 1920MHz to 1980MHz, fLO = 2300MHz to 2360MHz; TA = -40°C to +85°C. Typical values are at VCC = +2.85V, TA = +25°C,
unless otherwise noted.) (Note 1)
