US Patent Issued to PSEMI on March 4 for "Nonlinearity management in LNA bypass mode" (Texas Inventors)

ALEXANDRIA, Va., March 5 -- United States Patent no. 12,244,272, issued on March 4, was assigned to PSEMI Corp. (San Diego).

"Nonlinearity management in LNA bypass mode" was invented by Youngman Um (Austin, Texas) and Xiaoling Guo (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods and devices to improve nonlinearity performance of low noise amplifiers (LNAs) are disclosed. The described methods and devices reduce the capacitive loading of the LNA amplifying devices on the bypass path of the LNAs when operating in the bypass mode. This is performed by decoupling the active devices from ground to put the amplifying devices in a floating state, thus minimizing the impact of the gate-source ca...
