PRODUCTION DATA.
The VCO current is programmable and should be set according to operating frequency, RX/TX mode and output power. Recommended settings for the VCO_CURRENT bits in the VCO register are shown in Table 5-16 and are also given by SmartRF Studio. The VCO current for frequency FREQ_A and FREQ_B can be programmed independently.
The bias currents for the LNA, mixer and the LO and PA buffers are also programmable. The FRONTEND and the BUFF_CURRENT registers control these currents.
