Latest Patents

Shoujun Yang holds a patent for a "Low-loss, broad band, LC I/Q phase shifter." This invention includes an I/Q phase shifter and at least one LC balun. Compared to conventional phase shifters, his design primarily utilizes LC components, which significantly reduces losses. One embodiment of his phase shifter demonstrates a large bandwidth at a 77 GHz center frequency, with a 1 dB amplitude error bandwidth of approximately 40 GHz and a 1° phase error bandwidth of about 16.5 GHz. The use of inductors in his design, as opposed to the quarter wave transmission lines found in traditional phase shifters, allows for a reduction in chip area. Additionally, an emitter follower in his design helps maintain a relatively constant output, which is largely independent of various factors such as temperature and manufacturing variations.
