A recently granted patent (Publication Number: US11887945B2) discloses a packaged Doherty amplifier designed with innovative edge seal structures to protect transistors from chips or cracks during the singulation process. The amplifier includes main and peaking transistors integrated on a substrate, enclosed in a package with edge seal structures comprising metal layers and through vias connecting to a grounded conductor. Additionally, the patent covers the inclusion of on-die wire bonds and a third transistor with a corresponding edge seal structure for enhanced protection during manufacturing processes.

Furthermore, the patent details the specific types of transistors used in the amplifier, such as GaN-based HEMTs and LDMOS transistors, along with the operational frequencies ranging from 0.5 GHz to 40 GHz. The amplifier also features isolation structures, including recessed isolation structures and metal layers, to improve performance and reliability. The unique design elements, such as staggered rows of recesses and serpentine patterns for metal layers, contribute to the overall efficiency and functionality of the packaged Doherty amplifier as outlined in the granted patent.
