Abstract
A novel, simple and broadband 180° bit X-band phase shifter was proposed and fabricated in a standard micromachining process. It is composed of two 90° parallel-coupled lines; one of which is shorted and the other is grounded. Design equations for the proposed 180° bit phase shifter are derived by the method of even and odd mode analysis. Based on design equations, 180° bit phase shifter was designed and fabricated to operate from 7 to 13 GHz with ±5° of phase deviation.
