mismatch
range
Phase mismatch between the I and Q signals
between 1kHz to 12kHz.
Amount of gain change along I and Q paths
between 1kHz to 615kHz
VCO external time constant and PLL value
Tank LC's Q value should be above 20.
Measure @100kHz away from the mid-
frequency.
Select a VCO buffer output value reduced by
-2dB. Connect output load to 50 .
