| 发明名称 | Low-noise amplifier mixer with coupled inductors | ||
| 摘要 | A Radio Frequency Identification (RFID) reader configured to perform self-jammer cancellation (SJC) may include an SJC module coupled to a low-noise amplifier (LNA), which in turn may be coupled to a mixer via an LNA-mixer interface. The interface may be implemented with a horizontal matching circuit that includes four inductors magnetically and direct-current (DC) coupled to each other. In some embodiments, the inductors may each be implemented using a different segment of a single inductor. | ||
