1.7GHz to 2.5GHz, Direct I/Q Modulator with
VGA and PA Driver
Typical Operating Characteristics
(MAX2720/MAX2721 EV Kit, VCC = +3.0V, SHDN = VCC, ENX2 = GND, VPC = 2.5V, input I/Q signals driven in quadrature, from a
1kΩ source impedance, single-ended, fI+ = fQ+ = 500kHz, VI+ = VQ+ = 200mVp-p, PLO = -13dBm, fLO = 950MHz (MAX2720), fLO =
1157.5MHz (MAX2721), PDRIN = -12dBm, fDRIN = 1900MHz (MAX2720), fDRIN = 2315MHz (MAX2721), MODOUT and DROUT ports
are matched to a 50Ω load, TA = +25°C, unless otherwise noted.) (Note 1)
