Abstract
A thin-film filter may include a monolithic substrate and a patterned conductive layer formed over the monolithic substrate. The patterned conductive layer may include at least one thin-film inductor. The thin-film filter may have a power capacity that is greater than about 25 W. In some embodiments, the thin-film inductor(s) may be connected between the input port and the output port. A heat sink terminal may be exposed along the bottom surface of thin-film filter. In some embodiments, the heat sink terminal may have an exposed heat sink area, and the bottom surface of the thin-film filter has an area that is less than 20 times larger than the exposed heat sink area.
