ALEXANDRIA, Va., June 16 -- United States Patent no. 12,308,869, issued on May 20, was assigned to QUALCOMM Inc. (San Diego).

"Phase-reconfigurable circuits with programmable power splitting for dual-input power amplifiers" was invented by Guoxiang Han (San Diego), Paolo Enrico De Falco (San Diego) and Antonino Scuderi (San Diego).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase-reconfigurable circuit with programmable power splitting for a dual-input power amplifier is provided. The circuit includes an I/Q generator to generate I and Q RF signals from an input RF signal. A first vector-sum phase-shifter processes the I and Q RF signals to produce a first RF output signal. Similarly, a second vector-sum...
