Latest Patents
Yujian Han holds 1 patent for his invention titled "Switch-less connection for radio-frequency (RF) transceivers." This patent describes a switch-less transceiver that utilizes parallel LC resonances to function as OFF switches, while series LC resonances act as ON switches when resonating at the transmit (TX) or receive (RX) frequency. The design ensures that when the transmitter is disabled, no current flows through the series LC filters, providing an RF ground to the transmitter output node. The innovative use of a TX inductor and a TX blocking capacitor creates a high impedance that effectively blocks antenna signals from entering the transmitter when the receiver is disabled.
