Abstract: A method is provided. The method, comprises: power amplifying, with at least two parallel power amplifiers, at least two pre-distorted signals each corresponding to a unique transmit band, wherein each power amplifier operates in a unique transmit band; and pre-distorting, with a single pre-distortion system, at least two signals in different transmit bands, where the pre-distortion of each of the at least two signals is based upon a portion of a corresponding power amplified, pre-distorted signal, and where the pre-distortion diminishes certain IMD products in the corresponding power amplified, pre-distorted signal.

Abstract: In one embodiment, a RF signal repeater switchable between SISO and MIMO comprises: a controller; a first transmitter path switchably coupled to first donor and coverage antennas; a second transmitter path switchably coupled to second donor and coverage antennas; a first receiver path switchably coupled to the first donor and coverage antennas; a second receiver path switchably coupled to the second donor and coverage antennas. The controller configures the repeater for a MIMO TDD operating mode by: configuring the first transmitter path and the second receiver path to repeat at least a first MIMO channel of UE uplink RF signals and at least a first MIMO channel of base station downlink RF signals; and configuring the second transmitter path and the first receiver path to repeat at least a second MIMO channel of UE uplink RF signals and at least a second MIMO channel of base station downlink RF signals.

Abstract: To provide improvements in crest factor reduction in a distributed communication system, CFR configuration parameters can be determined based on communication signals received from a base station entity and distributed to node(s) of the distributed communication system. CFR engine(s) in the node(s) may perform CFR based on the CFR configuration parameters, and/or may adjust their CFR engine(s) based on signal parameters and/or operating parameters of a power amplifier coupled to a respective CFR engine. Some or all CFR processing may be offloaded from a node and assigned to optical transport card(s) of the system controller based on a processing bandwidth associated with the optical transport card(s).

Abstract: In one embodiment, a multi-transceiver RF signal processing system comprises: a controller; a DPD core and CFR engine; and a plurality of transceiver paths comprising at least a first transceiver path for a first frequency block, and a second transceiver path for a second frequency block. The first frequency block is adjacent to the second frequency block. Signal processing outputs a stream of digital RF based on wireless RF signals received into the first and second transceiver paths. Signal processing inputs a first stream of digital RF and outputs a first digital RF signal corresponding to the first frequency block to the first transceiver path, and outputs a second digital RF signal corresponding to the second frequency block to the second transceiver path for wireless transmission via the at least one antenna. The DPD core applies a distortion that covers the first and second frequency blocks.

Abstract: Systems and methods for RF hazard protection are provided. In one embodiment, a RF protection coupler comprises: a first port to couple to an output of an RF source circuit; a second port to couple to an external RF load; a source side and load side RF switches, wherein the source side RF switch and the load side RF switch are each switch between a first and second states in response to a detected matting. In the first state the source and load side RF switches establish an electrical path between the first and second ports. In the second state: the source side RF switch couples the first port to an impedance load that is impedance matched to the output of the RF source circuit; the load side RF switch couples the second port to an electrical ground; and a gap between the switches electrically isolates the ports.

Abstract: In an example, a receiver protection circuit includes a directional coupler configured to be coupled to a receive signal path of a communications device between an isolation device and an amplifier of the receive signal path. The receiver protection circuit further includes a power detector coupled to the directional coupler and configured to measure a power level of a transmit leakage signal in the receive signal path. The receiver protection circuit further includes a comparator configured to compare the measured power level of the transmit leakage signal in the receive signal path to a threshold value and output an alarm signal indicating that the measured power level of the transmit leakage signal exceeds the threshold value.
