  2. Attenuator (electronics) - Wikipedia

    en.wikipedia.org/wiki/Attenuator_(electronics)

    An RF microwave attenuator. Key specifications for attenuators are: [2] Attenuation expressed in decibels of relative power. A 3 dB pad reduces power to one half, 6 dB to one fourth, 10 dB to one tenth, 20 dB to one hundredth, 30 dB to one thousandth and so on.

  3. Π pad - Wikipedia

    en.wikipedia.org/wiki/Π_pad

    A Π-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers. A Π pad can be viewed as being two L sections back-to-back as ...

    A T-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers.

  6. Traveling-wave tube - Wikipedia

    en.wikipedia.org/wiki/Traveling-wave_tube

    Attenuators placed along the RF circuit prevent the reflected wave from traveling back to the cathode. Higher powered helix TWTs usually contain beryllium oxide ceramic as both a helix support rod and in some cases, as an electron collector for the TWT because of its special electrical, mechanical, and thermal properties.

  7. Function generator - Wikipedia

    en.wikipedia.org/wiki/Function_generator

    Function generators, like most signal generators, may also contain an attenuator, various means of modulating the output waveform, and often the ability to automatically and repetitively "sweep" the frequency of the output waveform (by means of a voltage-controlled oscillator) between two operator-determined
