RF Loads And Attenuators Have Compact Design

With extremely compact and lightweight design and low VSWR, 500 WT Series includes models that terminate or attenuate up to 500W of RF energy with a frequency range of dc to 2.5 GHz for applications such as cellular, data, ISM, Land Mobile, paging, PCS and SMR/ESMR. The loads weigh about 60% less and occupy only one-quarter the volume of other dry and oil dielectric loads of comparable wattage. Rated maximum VSWR is 1.10:1 at dc to 1 GHz and 1.25:1 at 1 to 2.5 GHz, and field tests have demonstrated VSWR of 1.04:1 or better at 470 to 860 MHz. Attenuators are 3, 6, 10, 20 and 30 dB.
