Abstract: A method of self-testing a transceiver integrated circuit substrate includes: providing a test signal to a transmission line that is communicatively coupled, or selectively communicatively coupled, to an input of a power amplifier of a first transceiver subcircuit of the transceiver integrated circuit substrate; providing the test signal from the transmission line to an LNA of an LNA of a second transceiver subcircuit of the transceiver integrated circuit substrate; and measuring the test signal before amplification by the LNA, or after amplification by the LNA, or both.

Abstract: Techniques are provided for configurable millimeter wave (mmWave) receiver architectures for carrier aggregation (CA). An example method for operating a wireless node in a carrier aggregation mode or a single band mode includes configuring the wireless node to operate in at least one of the carrier aggregation mode or the single band mode, configuring a high band receive chain wireless node to utilize a first intermediate frequency in response to configuring the wireless node to operate in the single band mode, and configuring the low band receive chain to utilize the first intermediate frequency, and the high band receive chain to utilize a second intermediate frequency in response to configuring the wireless node to operate in the carrier aggregation mode.

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.
