RECONFIGURABLE GPS/GALILEO INTEGRATED RF FRONT-END

摘要

PURPOSE: An RF(Radio Frequency) front end structure of a GPS(Global Positioning System)/ Galileo complex receiver is provided to receive diversity and simultaneously receive a combination of various signal bands. CONSTITUTION: A broadband LNA(Low Noise Amplifier)(110) amplifies low noise of a received navigation signal. Each unit receives an output signal of the broadband LNA. Each channel unit executes a switching, a filtering, and an amplifying process of a desired signal of the navigation signals. A control unit controls the switching, filtering, and amplifying process of the desired signal of the navigation in order to match the channel units with a band of the desired signal.
