I use a 4-layer board, on the top layer, there are 2530 and 2591, and I calculate the line width using the H which is the distance between the top layer and the second layer (GND layer) .
At the same time, I put a balun on the bottom layer. In the reference design of cc2530+2591, it seems that you calculate the line width using the H which is the distance between the bottom layer and the VDD layer (the 3rd layer) . If calculated using the H between the 2nd layer and the 4th layer, the line width should be much larger.
So the question is, why you choose the H of the distance between 3rd and 4th layer, but not the distance between 2nd and 4th layer? I think the H should be the distance between the layer which the Microstrip line is on and the GND layer.
Lookint forward to your answer.
