Latest Patents

Kang Ning's latest patents include groundbreaking work on methods and apparatus for supporting linearization on power combined power amplifiers. This invention describes a system that implements a power amplifier circuit assembly with an uneven power splitter, which feeds two power amplifiers of different classes. By supplying varying amounts of power to different amplifier circuits, the invention achieves an overall combined amplifier performance with a relatively uniform performance curve across a wide frequency range. In some embodiments, one amplifier is a class B power amplifier while the other is a class C power amplifier. Additionally, a phase shift may be introduced on a signal path to one of the amplifiers to compensate for differences in phase shifts introduced by the amplifiers used in parallel.

Another significant patent focuses on methods and apparatus for implementing a power-efficient amplifier device. This invention utilizes a primary and auxiliary power amplifier that operate as current sources providing current to the load. Capacitance coupling is employed to connect the outputs of the primary and secondary amplifiers. This combination achieves high average efficiency over the operating range of the device, making it well-suited for RF transmissions in the GHz frequency range, particularly around 30 GHz. In some embodiments, the primary amplifier is a class AB or B amplifier, while the secondary amplifier is a class C amplifier.
