    Response of geostationary communications satellite solid-state power amplifiers to high-energy electron fluence by Lohmeyer, Whitney, Carlton, Ashley, Wong, Frankie, Bodeau, Michael, Kennedy, Andrew, Cahoy, Kerri

    Published 2017
    “…We also find that the accumulated voltages reached are high enough to compromise components in the amplifier system, for example, the direct current (DC) blocking capacitor. An electron beam test using a representative coaxial cable terminated in a blocking capacitor showed that discharges could occur with peak voltages and energies sufficient to damage active RF semiconductor devices.…”

    Single antenna power measurements based direction finding : an FRI solution by Zhang, Song Bai

    Published 2010
    “…Determining the angle of arrival (AoA) for wireless source signals has great poten- tial practical applications, one example is beam forming in cellular communication. The conventional methodology used to determine the AoA mainly uses the an- tenna array as an acquisition system, and there are many signal process algorithms developed to retrieve the direction of arrival information. …”
