W-CDMA Upconverter and PA Driver
with Power Control
Typical Operating Characteristics (continued)
(MAX2383 EV Kit; VCC = +2.85V; SHDN = LO_EN = VCC, VGC = 2.0V; 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 through an interstage matching network; DROUT drives a 50Ω load impedance; fIF = 380MHz, fRF = 1950 MHz, fLO =
2330MHz; TA = +25°C.)
