US Patent 11791251 High power laminate RF package

The present disclosure relates to a package capable of handling high radio frequency (RF) power, which includes a carrier, a ring structure attached to a top surface of the carrier, an RF die attached to the top surface of the carrier within an opening of the ring structure and electrically connected to the ring structure, a heat spreader attached to a top surface of the ring structure, and an output signal lead configured to send out RF output signals generated by the RF die. Herein, the heat spreader covers a portion of the top surface of the ring structure at an output side of the package, and the output signal lead is attached to a top surface of the heat spreader. As such, the RF output signals are capable of being transmitted from the RF die to the output signal lead through the ring structure and the heat spreader.
