    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.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reconfiguring degeneration components in a converged RF transceiver supporting carrier aggregation across sub-6 GHz frequency bands and mmWave frequency bands. In a first aspect, an apparatus includes an input port configured to receive a mixer input signal; a first mixer forming at least a portion of an HRM mixer and coupled to the input port; a first configurable degeneration component of a first processing path coupled between the input port and the first mixer; and a controller coupled to the first degeneration component, wherein the controller is configured to control a first aspect of a first degeneration component. Other aspects and features are also claimed and described.

    Abstract: Aspects of the disclosure relate to devices, wireless communication apparatuses, methods, and circuitry for a t-switch with gate shunting. One aspect is an apparatus including a first differential switch having a control input. The apparatus further includes a second differential switch coupled to the first differential switch, the second differential switch a control input. A shunt capacitor is coupled between a first output and a second output of the first differential switch, and a first input and a second input of the second differential switch. A first shunt switch having a control input, an input, and an output has the input and the output coupled to the control input of the first differential switch. A second shunt switch having a control input, an input, and an output, has the input and the output coupled to the control input of the second differential switch.
