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: Disclosed is a sheet resistor designed to operate in a high frequency environment. Unlike conventional sheet resistors, the equivalent series inductance (ESL) is minimized or even eliminated altogether when using the designed sheet resistor. As a result, better signal isolation can be achieved.

Abstract: Certain aspects of the present disclosure provide techniques for training a digital pre-distorter (DPD) using real-time over-the-air transmissions and receptions by a user equipment (UE). A method for training the DPD generally includes transmitting a signal, generated by a transmitter front end, via a first port; sampling the signal, received over the air, at a second port; performing signal processing cleaning (e.g., synchronization, linear over-the-air channel estimation and equalization); calculating coefficients for a DPD; and configuring the DPD with the coefficients, for use in digitally pre-distorting sub sequent transmissions.
