Dear all,
I purchased evaluation board of adf4108

I am using the internal VCO and without changing anything

I connected 240MHz as reference signal (0dBm) to the board

I connected spectrum analyzer on VCO/2

VCO terminal wan not terminated nor any other port

I confegured the software correctly

the measured power of signal is -20dBm only on the VCO/2


is this normal? is there any thing I should do? or it is now burned?

is terminating VCO port is important?

Is it correct to use VCO/2 as an output port?




Thank you very much in advance
