LTC5599
Electrical Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TC = 25°C. VCC = 3.3V, EN = 3.3V, VCTRL = 3.3V, PLO = 0dBm, BBPI, BBMI, BBPQ,
BBMQ common mode DC voltage VCMBB = 1.4VDC, I and Q baseband input signal = 2MHz, 2.1MHz, 1VP-P(DIFF, I or Q), I and Q 90°
shifted, lower sideband selection, all registers set to default values, unless otherwise noted. Test circuit is shown in Figure 13.
