Abstract: In certain aspects, a method includes receiving a first intermediate frequency (IF) signal and a second IF signal via a common input, upconverting the first IF signal into a first radio frequency (RF) signal, transmitting the first RF signal via a first antenna array, upconverting the second IF signal into a second RF signal, and transmitting the second RF signal via a second antenna array. In a first transit mode, the first RF signal is in a first frequency band and the second RF signal is in a second frequency band, and, in a second transmit mode, the first RF signal and the second RF signal are both in the first frequency band.

Abstract: Devices and methods for detection of active return loss for an antenna element of a plurality of antenna elements of a phased array antenna are provided. An exemplary device can convert a voltage differential at an input of a power amplifier (PA) to first current. The device can convert a coupled voltage corresponding to a signal transmitted from the PA to a respective antenna element, to a second current. The device can convert a reflected voltage corresponding to a signal reflected from the respective antenna element, to a third current. The device can convert the first current, the second current, and the third current to an output voltage at a generator output. The device can further have a controller that can adaptively generate codebooks for transmission based on the output voltage.

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.
