Attenuators (6)

Bridged-T Attenuator

As its name implies, the bridged-T attenuator has an additional resistive element forming a bridged network across the two series resistors of the standard T-pad attenuator. This additional resistive element enables the circuit to reduce the level of a signal by the required atte...

Passive Attenuator Tutorial

The Passive Attenuator is a purely resistive network that is used to weaken or "attenuate" the signal level of a transmission line while improving the impedance match, making passive attenuators the opposite of amplifiers. Passive Attenuators are electrically connected between t...

Pi-pad Attenuator

The Pi-pad attenuator is so called because its basic layout and design resembles that of the Greek letter pi ( π ), meaning that it has one series resistor and two parallel shunt resistors to ground at the input and the output. The Pi-pad attenuator is another fully symmetrical...

T-pad Attenuator

Although not as common, this "T" (tee) configuration can also be thought of as a wye "Y" attenuator configuration as well. Unlike the previous L-pad Attenuator, which has a different resistive value looking into the attenuator from either end making it an asymmetrical, the T-pad ...

L-pad Attenuator

In its basic form, the L-pad Attenuator is nothing more than a very simple voltage divider network used in many electrical and electronic circuits to generate a lower voltage. The difference this time is that this type of attenuator is used in frequency dependent circuits to cre...

Passive Attenuators

Passive attenuators are basically two port resistive networks designed to weaken or "attenuate" (hence their name) the power being supplied by a source to a level that is suitable for the connected load. A passive attenuator reduces the amount of power being delivered to the con...
