TX VCO.
A fully integrated balanced VCO. The VCO frequency is controlled by the voltage applied to the VTUNE pin, and the applied
modulation voltage. Both have a negative sensitivity, i.e., as the voltage increases, the VCO frequency decreases. The base-band
must invert the transit modulation data to allow for this. The tuning voltage is referenced to V
CC
VCO.
The VCO is buffered to provide isolation against frequency pulling and reverse injection.
