Zusammenfassung:In certain aspects, a chip includes a pad, and a power amplifier having a first output and a second output. The chip also includes a transformer, wherein the transformer includes a first inductor coupled between a first terminal and a second terminal of the transformer, wherein the first terminal is coupled to the first output of the power amplifier, and the second terminal is coupled to the second output of the power amplifier. The transformer also includes a second inductor coupled between a third terminal and a fourth terminal of the transformer, wherein the third terminal is coupled to the pad. The chip also includes a first switch coupled to the fourth terminal, a shunt inductor coupled in parallel with the first switch, and a low-noise amplifier coupled to the third terminal.
