Abstract: Devices and method related to dual-sided radio-frequency package having substrate cavity. In some embodiment, a packaged RF device includes a packaging substrate configured to receive a plurality of components, the packaging substrate including a first side and a second side, the second side of the packaging substrate defining a pocket. The packaged RF device also includes a shielded package implemented on the first side of the packaging substrate, the shielded package including an RF circuit, the shielded package configured to provide RF shielding for at least a portion of the RF circuit. The packaged RF device further includes a component mounted substantially within the pocket of the second side of the packaging substrate.
