  • Vector voltage samplers for RF interface control of power amplifier
    Patent number: 8717104
    Abstract: A system for compensating impedance mismatch at an output terminal of a RF power amplifier is disclosed. In an embodiment, the system includes a plurality of samplers to measure a first set of parameters associated with an amplified signal being generated by the power amplifier. The first set of parameters is transmitted to a processing unit. The processing unit varies an impedance of an impedance element based on the first set of parameters. The impedance element is connected to the output terminal of the power amplifier.

  • Beam forming system
    Patent number: 7463193
    Abstract: A compact system can use modular components to enhance the isolation or quality of signals that an antenna array produces. The system can comprise an array of input coupler modules and an array of output coupler modules respectively on the input and output sides of a signal routing device. Each input coupler module can receive a signal from a specific element in the antenna array and can divide or split that received signal into a multiple signal components, such as seven. The signal routing device can route each of those signal components to a different output coupler module in the array of output coupler modules. Thus, each output coupler module can receive and combine multiple signal components, such as seven, from different input coupler modules. The signal routing device can include a readily manufacturable phase trimming section to compensate for phase mismatches.
