Abstract: A waveguide mechanical phase adjuster includes at least one pair of dielectric rods nominally spaced ¼ wavelength apart and inserted through a corresponding pair of holes in the wall of a waveguide. The holes are dimensioned so that they are in “cutoff” at the top end of the spectral band. An adjustment mechanism sets the insertion depth of the rods, which determines the amount of dielectric loading and, in turn, the insertion phase. Changing the insertion depth changes the dielectric loading, hence the insertion phase. The ¼ wavelength spacing of the rods serves to cancel reflected energy. Additional pairs of dielectric rods can be similarly configured and actuated to increase the range over which the insertion phase can be adjusted. The waveguide mechanical phase adjuster is well adapted for use with power combiners to maintain tight phase coherence between channels.
