Abstract
A Gunn diode oscillator tuning mechanism includes a waveguide wall formed with a cavity at the outside of the wall for accommodating a tuning mechanism. A tuning rod opening extends between the inside of the waveguide wall and the cavity to snugly accommodate a sapphire rod. A holder carries the fixed end of the sapphire rod and is slidable in the cavity. The holder is formed with a circumferential sectoral slot that engages an annular ring on the rotatable translatable shaft of a micrometer adjacent to the holder seated in a holding plate at the outside of the waveguide wall.
