Abstract
Devices and methods related to nested filters. In some embodiments, a radio-frequency device can include a substrate, and first and second filter devices mounted on the substrate with respective support structures, such that at least a portion of the second filter device is positioned in a space defined by an underside of the first filter device and the support structures for the first filter device. Such a radio-frequency device can be, for example, a packaged module for use in an electronic device such as a wireless device.
