Abstract: A wireless communication system and method that includes configurable Carrier Aggregation (CA) and/or Multiple-input Multiple-output (MIMO) operational modes. In CA, multiple carriers (i.e., channel bundling) are aggregated and jointly used for transmission to/from a single terminal. Downlink inter-band carrier aggregation increases the downlink data rates by routing two signals, received in different frequency bands, simultaneously to two active receivers in the RF transceiver. MIMO utilizes two additional receivers as diversity paths and the frequency generation can be shared between main and diversity path for each carriers.

Abstract: Embodiments provide improved systems and methods of gain control and calibration for wireless transmitters. In particular, embodiments allow linear gain control over the entire transmitter gain control range, independent of temperature/process variations. Embodiments require very low power consumption compared to existing approaches. Embodiments may also be used for gain control calibration during production time, thereby substantially reducing production calibration time and cost.

Abstract: A device implementing the subject scalable radio frequency communication system includes one or more primary radio frequency integrated circuits (RFICs) and at least one secondary RFIC. Each of the one or more primary RFICs is configured to receive an intermediate frequency (IF) signal from a baseband processor, upconvert the IF signal to a radio frequency (RF) signal, and transmit the RF signal to one or more secondary RFICs. The secondary RFICs under each of the one or more primary RFICs are configured to receive the RF signal from the corresponding primary RFIC, phase shift and amplify the RF signal, and transmit the RF signal via a plurality of antenna elements.
