Abstract
In this letter, a high‐performance 5‐bit CMOS phase shifter using a newly proposed 180° bit is presented for a Ku‐band mobile satellite phased array receiver. The 180° phase shifter exhibits good tolerance to substrate parasitic capacitances when compared with a conventional high‐pass/low‐pass type one. The designed 5‐bit CMOS phase shifter demonstrates a typical 11.7 dB ± 0.5 dB insertion loss and a 2.1° rms phase shift error at 12.2 GHz. © 2010 Wiley Periodicals, Inc.
