Stack assembly for radio-frequency applications. In some embodiments, a radio-frequency (RF) module can include a packaging substrate configured to receive a plurality of components, and an electro-acoustic device mounted on the packaging substrate. The RF module can further include a die having an integrated circuit and mounted over the electro-acoustic device to form a stack assembly. The electro-acoustic device can be, for example, a filter device such as a surface acoustic wave filter. The die can be, for example an amplifier die such as a low-noise amplifier implemented on a silicon die.

Disclosed are devices and methods related to radio-frequency (RF) shielding of RF modules. In some embodiments, tuned shielding can be achieved by utilizing different structures and/or arrangements of shielding-wirebonds to increase shielding in areas where needed, and to decrease shielding where not needed. Such tuning of shielding requirements can be obtained by measuring RF power levels at different locations of a module having a given design. Such tuned RF shielding configurations can improve the overall effectiveness of shielding, and can also be more cost effective to implement.

According to one exemplary embodiment, an overmolded package includes a component situated on a substrate. The overmolded package further includes an overmold situated over the component and the substrate. The overmolded package further includes a wirebond cage situated over the substrate and in the overmold, where the wirebond cage surrounds the component, and where the wirebond cage includes a number of wirebonds. The wirebond cage forms an EMI shield around the component. According to this exemplary embodiment, the overmolded package further includes a conductive layer situated on a top surface of the overmold and connected to the wirebond cage, where the conductive layer forms an EMI shield over the component.
