Typical Operating Characteristics (continued)

(MAX2720/MAX2721 EV Kit, VCC = +3.0V, SHDN = VCC, ENX2 = GND, VPC = 2.5V, input I/Q signals driven in quadrature, from a

1k

Ω 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 50

Ω load, TA = +25°C, unless otherwise noted.) (Note 1)
