Abstract:
1. A package for compact radio frequency signal system, comprising: a hybrid substrate with a sandwiched structure, and the hybrid substrate comprising a first dielectric layer and a second dielectric layer being separated by an interposer; wherein the first dielectric layer, located on one side of the interposer, with a first value of loss tangent carries one or more first components operable for transmitting radio frequency signal of at least one active component to at least one antenna arranged on top of the first dielectric layer; wherein the second dielectric layer, located on another side of the interposer, with a second value of loss tangent carries one or more second components operable for transmitting low frequency signal of at least one active component to at least one outside circuit; wherein the at least one active component is embedded in the hybrid substrate; and wherein the first value of loss tangent is lower than the second value of loss tangent; wherein at least one opening is formed through the interposer, and the active component is configured in the opening between the first and second dielectric layers, wherein at least one metal layer is formed on sidewalls of the opening to surround the active component, such that the metal sidewalls connecting with at least one first ground plate in the first dielectric layer and at least one second ground plate in the second dielectric layer constitute a self-shielding enclosure inside the package to protect the active component.
