Latest Patents
Qixian Shi holds a patent for a "Millimeter wave radio calibration circuit." This invention outlines a method for calibrating a radio transceiver by injecting a low-frequency tone at the transmit power amplifier input. The process involves upconverting the low-frequency tone to produce multiple tones at the amplifier output. It also includes determining which tone is associated with local oscillator feedthrough and which represents an in-phase and quadrature (I/Q) imbalance. The method further establishes a DC offset based on the local oscillator feedthrough tone and determines an I/Q offset associated with the amplifier output.
