Abstract: In certain aspects, a method is provided for measuring power using a resistive element coupled between a power amplifier and an antenna. The method includes squaring a voltage from a first terminal of the resistive element to obtain a first signal, squaring a voltage from a second terminal of the resistive element to obtain a second signal, and generating a measurement signal based on a difference between the first signal and the second signal. In some implementations, the resistive element is implemented with a power switch.

Abstract: In some aspects, an apparatus includes a transformer including a first inductor, a second inductor, and a third inductor. The apparatus also includes a power amplifier coupled to the first inductor, a first antenna coupled to a first terminal of the second inductor, a second antenna coupled to a second terminal of the second inductor, a first switch coupled between the first terminal of the second inductor and a ground, a second switch coupled between the second terminal of the second inductor and the ground, and a low-noise amplifier coupled to the third inductor.
