Abstract
This article presents the design of a 6‐bit phase shifter in a 0.18‐μm CMOS technology for X‐band phased array radar application. Meandered microstrip lines and compact circuit designs techniques yield a chip with 1.9 mm^2^ die area. The fabricated phase shifter demonstrates a typical 15.7 ± 1.1 dB insertion loss and a 4° rms phase shift error at 9.5 GHz. To the author's knowledge, this is the first demonstration of a 6‐bit phase shifter using CMOS switches with the lowest die area among reciprocal digital phase shifters at X‐band. © 2009 Wiley Periodicals, Inc.
