US Patent Issued to Georgia Tech Research on Oct. 27 for "D-band vector modulator phase-shifter with delay line-based differential quadrature generation" (Georgia Inventors)

ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,776,815, issued on Oct. 27, was assigned to Georgia Tech Research Corp. (Atlanta).

"D-band vector modulator phase-shifter with delay line-based differential quadrature generation" was invented by Arya Moradinia (Atlanta) and John D. Cressler (Atlanta).

According to the abstract* released by the U.S. Patent & Trademark Office: "An exemplary system and method are disclosed that employs a multi-bit D-band vector modulator phase shifter that couples to a transmission line-based delay input line structure for a phased array circuit. The exemplary system and method can generate differential quadrature signals that can be weighted by amplifiers and cascaded with a buffer amplifier to achiev...
