E-Band 4-Bit Phase Shifter using SP4T Flip Chip Switches

摘要

A 4-bit millimeter-wave switched delay line phase shifter is presented. The phase shifter is designed using commercially available SP4T flip-chip MMICs attached to an alumina sub-strate. The module operates in the E-Band from 82 - 84 GHz and has an average insertion loss of 20 dB. The size of the module is 10mm x 7.5 mm. This paper presents a cost effective 4-bit E-Band phase shifter.
