Designing RF, Mixed-technology Printed Circuit Boards

Printed circuit boards with both analog and digital circuitry are nearly universal. Recently, integration of RF circuitry in addition to the mixed analog and digital circuits has become more common. Problems arise because the PCB design tools have been ignorant of RF shapes printed on the board and a great deal of manual work was required to achieve a functioning product. Mentor has teamed with RF Design Tool suppliers, such as Agilent, to bring to market the first integrated RF-PCB system tool.
