    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.

    IPC: H04B1/525

    Abstract: Wireless signal processing may be improved by using a configurable baseband filter (BBF) in the receive path of a transceiver. A configurable BBF may accommodate processing of different wireless signals in a single integrated circuit (IC) chip. For example, a single IC may support processing of 5G mmWave RF signals and 5G sub-7 GHz RF signals by reconfiguring the BBF with settings appropriate for the different wireless signals. The reconfiguring of the BBF may include adjusting a bandwidth of the BBF and/or adjusting a filter order of the BBF. The reconfiguring of the BBF may be performed in response to detection of jammer signals to improve rejection of the jammer signals.

    Abstract: A carrier aggregation diversity antenna module with integrated low noise amplifier banks is disclosed. In an exemplary embodiment, an apparatus includes at least one switch configured to establish a transmit signal path to transmit an uplink signal from at least one diversity antenna and to establish a receive signal path to receive downlink diversity signals from the at least one diversity antenna. The apparatus also includes band selection filters configured to filter the downlink diversity signals to generate at least three diversity band signals. The apparatus also includes a multiplexing amplifier configured to amplify the diversity band signals to generate at least three amplified diversity band signals that are output to a transceiver.

    Abstract: Expandable transceivers and receivers supporting operation on multiple frequency bands and multiple carriers are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit (IC) chip, or circuit module) includes a low noise amplifier (LNA) and interface circuit. The LNA resides on an IC chip and includes a first/on-chip output and a second/off-chip output. The interface circuit also resides on the IC chip, is coupled to the second output of the LNA, and provides an amplified RF signal outside of the IC chip. The apparatus may further include a buffer, load circuit, and downconverter circuit. The buffer resides on the IC chip, is coupled to the first output of the LNA, and receives a second amplified RF signal from outside of the IC chip. The load circuit is coupled to the first output of the LNA. The downconverter circuit is coupled to the load circuit.
