The integration of passive components onto a module platform offers great potential for miniaturization of RF and microwave systems. Development of component design with respect to electrical requirements is one of the challenges in RF system design. This paper first introduces a layout synthesis algorithm for embedded passive components like capacitor, resistor and inductor. For required electrical parameter of embedded passives (main values) including RF characteristic (resonant frequency, quality factor, 3dB cutoff frequency) the optimized component layout are generated. For electrical simulation respective s-parameter and equivalent circuit model are derived. This synthesis procedure is a break through for modern RF system design. The synthesis algorithm is universal and can be applied easily for various design types of embedded inductors, capacitors and resistors. The method is demonstrated using HDI organic square loop inductors as a specific example.
