FINER RESOLUTION GAIN REGULATION

The data shown in the Performance vs. Gain Regulation section

is shown based on VCTRL2 and VCTRL3 being equal. Finer

resolution of the gain regulation can be obtained if VCTRL2 and

VCTRL3 are used separately. Note that the overall dynamic

range stays the same. Figure 57 through Figure 60 show the

output IP3 and conversion gain when VCTRL2 and VCTRL3 are

used separately.

Figure 57 and Figure 58 show the upper sideband performance

for RFOUT at 23 GHz. Figure 59 and Figure 60 show the lower

sideband performance for RFOUT at 18 GHz. In Figure 57 and

Figure 59, VCTRL3 is held constant at −5 V, and VCTRL2 is

swept from −5 V to −0.75 V. When VCTRL2 = −0.75 V, VCTRL3

is swept from −5 V to −0.75 V. In Figure 58 and Figure 60,

VCTRL2 is held constant at −5 V, and VCTRL3 is swept from

−5 V to −0.75 V. When VCTRL3 = −0.75 V, VCTRL 2 is swept

from −5 V to −0.75 V.
