摘要： Front end systems and related devices, integrated circuits, modules, and methods are disclosed. One such packaged module includes a multi-mode power amplifier circuit in an interior of a radio frequency shielding structure and an antenna external to the radio frequency shielding structure. The multi-mode power amplifier circuit includes a stacked output stage including a transistor stack of two or more transistors. The multi-mode power amplifier circuit also includes a bias circuit configured to control a bias of at least one transistor of the transistor stack based on a mode of the multi-mode power amplifier circuit. The radio frequency shielding structure can extend above a package substrate. The antenna can be on the package substrate. Other embodiments of front end systems are disclosed, along with related devices, integrated circuits, modules, methods, and components thereof.

摘要： Reconfigurable antenna systems with ground tuning pads are provided herein. In certain configurations, an antenna system includes a module substrate including a ground plane and a ground tuning pad configured to receive a ground voltage from the ground plane. The antenna system further includes an antenna element and a tuning conductor that is spaced apart from the antenna element and operable to load the antenna element. Furthermore, a switch is electrically connected between the tuning conductor and the ground tuning pad, and operates to selectively connect the tuning conductor to the ground plane by way of the ground tuning pad to provide tuning to the antenna element.

摘要： Reconfigurable antenna systems with ground tuning pads are provided herein. In certain configurations, an antenna system includes an antenna element, a first tuning conductor spaced apart from the antenna element on a first side of the antenna element, a second tuning conductor spaced apart from the antenna element on a second side of the antenna element, a first ground tuning pad configured to receive a ground voltage, and a first switch electrically connected between the first tuning conductor and the first ground tuning pad. The first switch is operable to selectively connect the first tuning conductor to the first ground tuning pad to thereby tune the antenna element.

摘要： Reconfigurable antenna systems integrated with a metal case are provided herein. In certain embodiments, user equipment (UE) for a cellular network includes a metal case and an antenna system for transmitting and/or receiving wireless signals. The antenna system includes a tuning conductor formed in the metal case, a patch antenna element that is spaced apart from the tuning conductor, and a switch electrically connected in series between the tuning conductor and a ground voltage. The switch electrically connects the tuning conductor to the ground voltage in an on state and electrically disconnects the tuning conductor from the ground voltage in an off state.

摘要： Integrated Doherty power amplifiers are provided herein. In certain implementations, a Doherty power amplifier includes a carrier amplification stage that generates a carrier signal, a peaking amplification stage that generates a peaking signal, and an antenna structure that combines the carrier signal and the peaking signal. The antenna structure radiates a transmit wave in which the carrier signal and the peaking signal are combined with a phase shift.

摘要： Aspects of this disclosure relate to selectively shielded radio frequency modules. A radio frequency module can include a package substrate, a radio frequency component on the package substrate, a multi-layer antenna, a radio frequency shielding structure configured to provide shielding between the multi-layer antenna and the radio frequency component. The radio frequency shielding structure can include a shielding layer providing a shield over the radio frequency component and leaving the radio frequency module unshielded over the antenna.
