    摘要: The specification describes PDA (SD/MMC) devices and PDA cards wherein the substrate on which the PDA components are mounted comprises two tiers. Components with a high profile are mounted on the lower tier, and devices with normal or low heights are mounted on the upper tier. The upper tier is contained in the portion of the card conforming to, for example, the 1.4 mm SDA standard thickness, while the lower tier is formed in the portion of the card that allows a larger thickness, for example SDA standard thickness 2.1 mm.

    摘要: Balun transformers are described wherein multiple transformer loops are implemented in a stacked design with the primary and secondary loops overlying one another. By aligning the loops in a vertical direction, instead of offsetting the loops, the area of the device is reduced. Multiple transformer loops are nested on each level, and the transformer loops on a given level are connected together using a crossover located on a different level.
