    Abstract: Aspects of a wireless apparatus for configuring a plurality of VCOs are provided. The apparatus may be a UE. The UE receives a configuration for a plurality of carriers. Each carrier corresponds to a different LO frequency. In addition, the UE determines a VCO frequency for generating each LO frequency. Further, the UE assigns each determined VCO frequency to each of a plurality of VCO modules based on a distance between the VCO modules and each of the determined VCO frequencies. The plurality of VCO modules are of a set of VCO modules including at least three VCO modules.

    Abstract: An aspect relates to a filter or a first gyrator including a first set of cascaded inverters, and a first set of one or more passive devices coupled to the first set of cascaded inverters. Another aspect relates to a method including applying an input signal to an input of a first one of a set of cascaded inverters coupled to a set of one or more passive devices, and receiving an output signal from the set of cascaded inverters, the output signal being a filtered version of the input signal. Still another aspect relates to a transceiver including a filter with a first set of cascaded inverters, and a first set of one or more passive devices coupled to the first set of cascaded inverters; and a mixer coupled to the filter.

    Abstract: A radio frequency (RF) front-end receiver having a passive mixer with feed-forward intermodulation distortion cancellation, or at least reduction. An example receiver generally includes a mixer having differential input terminals and differential output terminals and a baseband filter having inputs coupled to the differential output terminals of the mixer. The receiver also includes common-mode sensing circuitry coupled to the differential input terminals of the mixer and configured to sense a common-mode signal of a first differential signal present at the differential input terminals of the mixer. The receiver further includes a conversion circuit coupled to the common-mode sensing circuitry and configured to convert the common-mode signal to a second differential signal presented to the differential output terminals of the mixer and the inputs of the baseband filter.

    Abstract: Certain aspects of the present disclosure provide multi-way diversity receivers with multiple synthesizers. Such a multi-way diversity receiver may be implemented in a carrier aggregation (CA) transceiver. One example wireless reception diversity circuit generally includes three or more receive paths for processing received signals and two or more frequency synthesizing circuits configured to generate local oscillating signals to downconvert the received signals. Each of the frequency synthesizing circuits is shared by at most two of the receive paths, and each pair of the frequency synthesizing circuits may generate a pair of local oscillating signals having the same frequency.

    Abstract: Carrier aggregation (CA) may cause interference between operation on two or more carriers within a user equipment (UE). This interference can degrade signal quality on one or more of the carriers involved in the carrier aggregation, which may be referred to as “desensing” one or more carriers. One or more isolating buffers may be coupled at a down-conversion mixer at a point where the down-conversion mixer receives a signal from a transmission line for isolating the transmission line from other transmission lines. The isolating buffer may reduce the effect of interference between multiple transmission lines carrying different carriers during carrier aggregation (CA) operation. The isolating buffers may be used in an RF transceiver supporting both 5G sub-7 GHz and 5G mmWave wireless networks and carrier aggregation across sub-7 GHz and mmWave bands.
