I have extensive knowledge and experience in printed circuit board design and layout. I have designed every kind of PCB from simple 1-layer boards to highly complex 16-layer boards with multiple ground and power planes and impedance controlled embedded microstrips and striplines. I am an expert in the use of specialized laminate materials such as those available from Rogers corporation for many applications including RF. I used many different EDA tools, but I specialize in Altium Designer and OrCAD. I also do simulations and modeling using tools like PSPICE.
