Wideband Digital Phase Shifter with Low Insertion Loss

Abstract

Abstract. In this paper, we first analyze the structure of the commonly used phase shifter and analyze its characteristics. Secondly, after choosing the high-pass and low-pass filter structure to design the phase shifter, the characteristics of the phase shifter are analyzed and selected respectively. , The simulation results meet the design requirements. The circuit has been through 0.5μm GaAs process, simulation tools for ads2011. The phase shifter designed over the entire operating frequency band exhibits good performance.
