TYPICAL CHARACTERISTICS: Two-Tone Baseband (continued)
VCC = 3.3 V; TA = +25°C; LO = 0 dBm, single-ended drive (LOP); I/Q frequency (fBB) = 4.5 MHz, 5.5 MHz; baseband I/Q
amplitude = 0.5-VPP/tone differential sine waves in quadrature with VCM = 0.25 V; and broadband output match, unless
otherwise noted.
