Abstract :
A novel, simple and broadband 180deg; bit X-band phase shifter was proposed and fabricated in a standard micromachining process. It is composed of two 90deg parallel-coupled lines; one of which is shorted and the other is grounded. Design equations for the proposed 180deg bit phase shifter are derived by the method of even and odd mode analysis. Based on design equations, 180deg bit phase shifter was designed and fabricated to operate from 7 to 13 GHz with plusmn5deg of phase deviation
