The output power problem of ADF4351

Question asked by XingLi on Apr 17, 2018

1.Can ADF4351 output power of 2dBm at single  in 40MHz~4.4GHz? Power fluctuation is 2dBm

2.Can auxiliary output B also output 2dBm power at single ended output? Can the power fluctuation be 2dBm?

3.In my test, it is found that the power of the auxiliary output B is lower than the main output A power, which is the characteristic of the chip itself, or is my own circuit to be improved.


I hope to get answers and suggestions from the engineers concerned. Thank you!
