The EHA series of high power continuous variable attenuators can be used to adjust the power signal level countinuously within centrain freqency range without power off, they can also be used to adjust power level of test systems as inset attenuators, with high accuracy and high stability.

EHA100 series can hangle average power of 100W, operates at frequency range 0.9-4GHz with bandwidth of 100MHz and low VSWR.
