Abstract :
A novel, simple and broadband 90° bit C-band phase shifter was proposed and fabricated by LTCC process. It is composed of an 180° transmission line and two 90° shorted transmission lines. Design equations for the proposed 90° bit phase shifter are derived by admittance parameter analyses. Based on the design equations, a broadband a 90° bit phase shifter with ±2° of phase deviation was designed and fabricated.
