i use ADF5901 with ADF4159. But i have two questions about ADF5901.
1. Does the output power of TX out of ADF5901 can be changed from -20dBm to +8dBm by change the Tx AMP CAL REF CODE? i connect a amplifier after ADF5901. So I should check this.
2. I think the VCO-CAL in ADF5901 is useless when i use ADF4159 to control the Vtune of VCO in ADF5901. So i want to know how do i set the N-Divider and R-Divider in ADF5901?
Because in a PLL，the N-divider and R-divider i really use is in PLL just the ADF4159 but not in VCO just the ADF5901.
look forward for your reply.
