Millimeter Wave Phase Shifter
Abstract
The desired variation in phase shift is produced by electronic modulation of the width of a rectangular waveguide which results in a change in the phase shift per unit length along the waveguide. The change in effective width of the waveguide is accomplished by means of a PIN diode that is literally distributed along a sidewall of the waveguide. Among the tasks required study were (1) propagation analysis for the diode-loaded waveguide to determine the relevant parameters, (2) fabricating and evaluating the distributed PIN diodes, and (3) forming a phase shifter using these diodes. Computed and measured data are presented for waveguides loaded with silicon slabs of various conductivities and for distributed PIN diodes. The work demonstrated the potential feasibility of the distributed PIN phase shifter.
