The on-chip VCO operates at 2 x the output frequency. The divide by 2 at the output of the VCO reduces the amount of PA feedthrough. As a result of this, OOK modulation depths of greater than 50 dB are easily achievable. The FSK_ADJ and ASK_ADJ resistors can be adjusted in the system to optimize output power, for each modulation scheme. An additional 1.5 dB of output power is provided for the lower bank of channels to adjust for antenna performance. The CE line allows the transmitter to be powered down completely. In this mode, the leakage current is typically 0.1 A.
