  • TDMA rate reconfigurable matrix power amplifier and method of communication in a FDMA/TDMA architecture
    Patent number: 9954632
    Abstract: A communication system including a communication platform, and a downlink communication module connected to the communication platform and having a matrix power amplifier, the matrix power amplifier including an input hybrid matrix, an output hybrid matrix, a bank of high power amplifiers disposed between and in communication with at least the input hybrid matrix and the output hybrid matrix, and a bank of adjusters disposed between and in communication with at least the input hybrid matrix and the output hybrid matrix. The communication system further includes a driver circuit connected to each adjuster in the bank of adjusters, the driver circuit being configured to command each adjuster to modify communication signals, passing through the matrix power amplifier, at time division multiple access rates.

  • Multi-port amplifier utilizing an adjustable delay function
    Patent number: 9735742
    Abstract: Disclosed is a multi-port power amplifier (“MPA”) having an input hybrid matrix (“IHM”), an output hybrid matrix (“OHM”), and a plurality of high-power amplifier (“HPA”) chains. The MPA may include a plurality of adjustable delay modules (“ADMs”) in signal communication with the IHM and the plurality of HPA chains. Each adjustable delay module (“ADM”) of the plurality of ADMs may be in signal communication with the IHM and a corresponding HPA chain of the plurality of HPA chains.
