  • Radio transmitter
    Patent number: 12665621
    Abstract: A transmitter has a port configured to receive a transmit signal, a first power amplifier connected to the port, a second power amplifier connected to the port, a power supply switch configured to selectively couple one of a first supply voltage terminal or a second supply voltage terminal to one of a supply terminal of the first power amplifier or a supply terminal of the second power amplifier, a first antenna output terminal connected to the first power amplifier, a second antenna output terminal connected to the second power amplifier, and a control unit configured to control the power supply switch based on a transmitter power requirement to provide an amplified transmit signal based on the transmit signal at one of the first antenna output terminal or the second antenna output terminal.

  • STACKED DIE PACKAGE WITH ELECTRICAL SHIELDING PLATE
    Publication number: 20260026356
    Abstract: A semiconductor package structure includes a substrate with a substrate surface, a processing device electrically coupled to the substrate surface, one or more radio frequency integrated circuits (RFIC(s)) electrically coupled to the substrate surface, and a shield plate. The shield plate is disposed between the one or more RFIC(s) and the processing device and is configured to couple the one or more RFIC(s) to a package ground via one or more conductors. The package ground has a ground voltage associated with the semiconductor package structure.
