A designing solution for the C-band digital phase shifter

Abstract

Nowadays, phase shifters are widely applied in modern radar and electronic warfare systems. The design of phase shifters is becoming more and more compact, with large phase coverage, high max input power, and high efficiency at a lower cost. This paper presents technical solutions and technology used in designing of C-band phase shifter. The phase shifter uses multiple PIN diodes in combination with the stripline in order to reduce the overall size while ensuring the accuracy of the phase shift step according to design requirements.
