Abstract :
Computations of operating temperatures in microfabricated upper-millimeter-wave sheet beam traveling wave structures are provided. The studies include the effects of different cooling techniques and construction materials. The scaling of output power capability vs. frequency, as constrained by thermal limits, is also presented.
