Manufacturers : RF and microwave electronics : Microwave attenuators

In many microwave systems attenuators are used for automatic gain control of receiver and transmitter systems. Fixed and variable microwave attenuators provide gain level adjustments for microwave circuits and systems. Attenuators are also used for amplitude weighting in phased array radar and for temperature compensation of microwave amplifiers. Microwave attenuators provide attenuation in either discrete step attenuation or continuously variable. Broadband microwave attenuators typicallybcontain a single resistive surface which forms both the series attenuated path between the primary conductors and a shunt impedance path between the primary conductors and the ground conductor. Generally, microwave attenuators operate by absorbing the electromagnetic energy of a wave traveling down the wave guide. The amount of attenuation may be varied by changing the insertion depth of an absorbing element.
