settings for default FMCW 5.7 to 5.8 GHz

Hi,

This tutorial might help you to simulate and extract ramp parameters. After deciding the ramp parameters, you can use the eval board GUI to set the register values.

Thank you Very much for your quick response. We have seen this video, when we are checking the signal in spectrum analyzer for more than 20 MHz Bandwidth Specrum is jumping, that is why we want to cross check the basic working settings for the default eval board and verify whether we are in right direction or not.Please, can you share the working design example if you have.

Hi, 

ADF4158 GUI provides default register values for 5.8 GHz operation with the EVAL board. After that, you can enter ramp parameters calculated using ADISimPLL. 

For example: 

Please be aware that VCO on the evaluation board has a range from 5.725 to 5.875 GHz. The loop filter is designed to have a 20Khz bandwidth. 

Thanks,
