Latest Patents
One of Schwan's latest patents is titled "Method and apparatus for integrating power amplifiers with phase locked loop in a single chip transceiver." This innovation focuses on integrating a phase-locked loop and power amplifier on a single chip while eliminating cross-talk between components. To achieve this, a frequency translation block is introduced to change the output frequency of the PLL. Additionally, a high isolation buffer is implemented to prevent unwanted feedback, and the voltage supply domains for each component are physically separated to further enhance isolation.
Another notable patent is "Method and apparatus for the integration of a high efficiency power amplifier with an integrated transceiver for wireless communication." This invention features an integrated transceiver that includes both a frequency determining means and a power amplifier. A transmission filter is utilized to suppress unwanted spurious outputs in the integrated circuit before the power amplifier stage amplifies and transmits the desired signal. Furthermore, a differential to single-ended converter is implemented to enhance efficiency.
