AWR2944: VCO selection for AWR2944

Part Number: AWR2944

Hi Experts

When trying to construct a new profile in AWR2944, There are 3 different VCO for candidate.

in DFP it says 

Since VCO2 could cover 77-81Ghz,  it seems  always a much better choice comparing to VCO1.  

Is there any difference except the frequency range we need to concern before chose the VCO? 

Thanks

    Hi,

    If the application requires only 76-78GHz, it is better to use the VCO1. The reason for this is that the VCO calibration will be optimized for this range.

    If the application requires a wider bandwidth, than use VCO2

    thank you
