Latest Patents
One of Murji's latest patents is titled "Method and apparatus for power supply modulation of a radio frequency signal." This invention allows a transmitter power supply to modulate an RF signal without the need for a calibration or training cycle every time an exciter or power amplifier module is switched in and out or when the transmitter powers up. During the calibration of the exciter module, a delay factor is determined and stored for each signal modulation scheme. The power amplifier module generates a power supply voltage based on the envelope signal and a final delay factor, which is derived from the exciter module and power supply modulation delay factors. This innovative approach enhances the efficiency and reliability of RF signal transmission.
Another significant patent by Murji is "Method and apparatus for alarming in a power supply modulated system." This invention presents a communication device that incorporates multiple processors and a power amplifier. One processor receives signals from a monitor to indicate the presence of an alarm, while another processor adjusts the modulation of the power supply based on the type of alarm detected. This ensures that the power supply voltage is optimized or maintained during fault conditions, thereby improving the overall performance of the power amplifier.
