  • Analog signal processing device for phased array antennas
    Patent number: 9219446
    Abstract: A signal processing device includes a device package, processing circuitry and biasing circuitry. The processing circuitry is packaged in the device package and is operative to receive one or more Radio Frequency (RF) input signals from one or more antenna elements via one or more pre-amplifiers that are separate from the device, and to process the RF input signals so as to produce an RF output signal. The biasing circuitry is packaged in the device package and is operative to produce one or more biasing signals for biasing the pre-amplifiers.
    Type: Grant
    Filed: October 1, 2013
    Date of Patent: December 22, 2015
    Assignee: Gilat Satellite Networks, Ltd.
    Inventors: Ilan Barak, Borislav Marinov, Alexander Kostov, Bojidar Avdjiski, Radosvet Arnaudov
