摘要： System and method for implementing a link aggregation system, a protection system, and an XPIC application for an all outdoor radios system using a wireless channel operating at a license-free 60 GHz band are provided. The license-free 60 GHz band offers a wide frequency bandwidth that can support a high speed data rate up to 10 Gbps in full duplex mode, frequency reuse, and high security due to its fast oxygen absorption at 60 GHz. As such, a wireless channel operating at the license-free 60 GHz band may be used for a link aggregation system to support wireless local area network (LAN) connections with the speed up to 7 Gbps. In addition, a wireless connection operating at the license-free 60 GHz band may be used to support both XPIC application and protection system for all outdoor radios to achieve a transmission speed of up to 10 Gbps in a full duplex mode.

摘要： A digital microwave radio system includes a splitter that splits a common baseband input into two baseband outputs, first and second transmitters, each transmitter electrically connected to a baseband output of the splitter via a mixer, a common local oscillator electrically connected to the mixer of the first transmitter and the mixer of the second transmitter via an adjustable phase shifter, respectively, and a combiner. The common local oscillator is configured to up-convert each baseband output into a radio-frequency signal using a corresponding mixer. The combiner combines the two radio-frequency signals into a 0-degree phase-shift output and a 180-degree phase-shift output, respectively. A phase error control loop adjusts the phase shifter to minimize the 180-degree phase-shift radio-frequency output. A combiner gain control loop adjusts the output power level of the two transmitters in accordance with an actual power detector reading at the 0-degree phase-shift radio-frequency output.

摘要： Various embodiments provide for systems and methods for increased linear output power of a transmitter. An exemplary wireless communications system for transmitting an input signal comprises a predistorter module, a GaN power amplifier, a coupler, and an antenna. The predistorter module is configured to detect existing distortion by comparing the input signal to a feedback signal and generate a correction signal. The predistorter may adaptively adjust its operation to minimize the existing distortion due to GaN power amplifier nonlinear characteristics. The result is that the GaN power amplifier may send a power signal of improved linearity to the antenna. The coupler is configured to sample the amplified signal from the GaN power amplifier to generate the feedback signal. The antenna is configured to transmit the amplified signal.
