WCDMA Quasi-Direct Modulator
with VGA and PA Driver
AC ELECTRICAL CHARACTERISTICS
MAX2395 EV kit, VCC = +2.7V to +3.3V, RBIAS = 12kΩ, VVGC adjusted to obtain maximum rated output power, and TA = -40°C to
+85°C. I/Q inputs driven differentially with low- impedance source based on 3GPP UpLink reference measurement channel
(12.2kbps), envelope level 1VP-P. Typical values are at VCC = +2.85V and TA = +25°C, unless otherwise noted. See Tables 1 and 3 for
register settings.) (Note 2)
