    en.wikipedia.org/wiki/160th_Fighter_Squadron

    The RF-80's were responsible for the daylight operations; the RB-26s for night photography. In June 1952, the 117th was involved in Exercise 'June Primer'. This exercise took place in an area bordered by a line drawn from Cherbourg to Geneva in the east and in the west by the Swiss, Austrian and Russian occupation zone borders.

  7. RF and microwave filter - Wikipedia

    en.wikipedia.org/wiki/RF_and_microwave_filter

    Radio frequency (RF) and microwave filters represent a class of electronic filter, designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). It is component that is used in electronic systems to pass or reject specific frequencies and attenuate of unwanted signals within the ...

  8. RF front end - Wikipedia

    en.wikipedia.org/wiki/RF_front_end

    In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1] It consists of all the components in the receiver that process the signal at the original incoming radio frequency (RF), before it is converted to ...

  9. Frequency agility - Wikipedia

    en.wikipedia.org/wiki/Frequency_agility

    Frequency agility is the ability of a radar system to quickly shift its operating frequency to account for atmospheric effects, jamming, mutual interference with friendly sources, or to make it more difficult to locate the radar broadcaster through radio direction finding.
