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: 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: In one example, a system includes a radio frequency port coupled to an external connector and a microstrip line coupled to the radio frequency port and one or more components mounted on a printed circuit board. The system further includes a short coupled to the microstrip line and a ground reference, wherein the short is coupled to the microstrip line proximate the radio frequency port.
