Hello.
I decided to modify the PCB material of the MRF6V2150N component for cost reasons, its datasheed suggests Arlon CuClad 250GX - 0300--55--22, 0.030 ″, εr = 2.55, but replaced by FR4, I made the layout adjustments to continue with 50homs, but in the tests done, I noticed that the gain is in a different frequency, it should be 414 MHz and it is in 370MHz.
Does anyone have any suggestion of what may have happened. Thanks
