Thanks Kapil.
I had avoided analog signals running on the split plane. Is the same constraint applicable to the traces which carry dc current also? And I didn't get what you meant by command ground...

Kapil,
Attached is the board I am working on. Its a two layer board with routing on both the layers. I have used copper pours as ground on the bottom layer. Analog signal is routed on the top layer, beneath which I have created the analog ground separation. The rest of the board is covered with...
Hi,
I am a newcomer in RF board design. The analog signal on the board is of 2.4GHz. I am using 1.8V dc supply to the board. Do I need to split my ground plane so as to provide return current path to the analog signal, which then gets separated from the return path of dc current? Is it...
Hi,
One of my components in my PCB needs a footprint which contains a T-Shaped pad. Is it possible to draw this in Orcad-Layout? Normally I see square/circular/rectangular pads. Can we assign an arbitrary shape to a pad? How can it be done?
Thanks in advance

Hi,
I have a RF-PCB layout done in OrCad. I want to simulate the PCB and analyze its performance. I have both passive components (R-L-C) and active components(ICs) in my design. Which tool does support simulation of Orcad Layout? Can I incorporate the behavior of certain components (like S...
Hi,
I have done my pcb design in Orcad Layout. In the design, I had to connect the center pads of the IC foot print to ground. I used free via in the center pad for this. I had run DRC check prior to creating the Gerber file and it showed no error. But, the Gerber file is not showing the...
Hi,
I have a .s4p file for a balun. Is it possible to get S-Parameter plots from the file? Can somebody suggest the way to do it?
Thanks in advance,

Thanks marce for the reply.
I am designing an RF PCB in which some signal traces need 50 ohms impedance matching. For this I had to use 74 mils track width with the manufacturing info I have. But the ICs in my board are very small(3X3 millimeter sq) and the pin pads are of 10 mils. So...
Hi all,
I am also facing the same problem. In my design I need a track with its width changing from 74 mils to 10 mils. But it doesn't look good at the point where the width change happens. My question is, is it possible in orcad layout to provide a gradual change of the track width along...
