Abstract: A wideband amplifier includes a first stage and a second stage. The first stage includes a transconductance transistor driven by an input signal through an input transformer. The transconductance transistor couples to a cascode transistor forming an output node for the first stage. The second stage couples the output node from the first stage through an output transformer to drive an output transistor.

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: Aspects of the present disclosure relate to a receiver including an amplifier circuit. The amplifier circuit includes a common-source amplifier having an input and an output, and a common-gate amplifier having an input and an output, wherein the input of the common-gate amplifier is coupled to the output of the common-source amplifier. The receiver also includes a first receive chain coupled to the output of the common-gate amplifier, and a second receive chain coupled to the output of the common-source amplifier.
