A Q‐band bidirectional transceiver has been designed and fabricated for millimeter‐wave CMOS phase array systems. The proposed design replaces several switches previously required for a bidirectional approach with a compact double‐pole double‐throw switch. Phase shifting is performed in 90° step using a high‐pass/low‐pass structure, and the transceiver demonstrates a highly linear phase response. Over the frequency of 35 to 40 GHz, the measured root‐mean‐square phase error is <5.5° and <12.1° for transmitter and receiver paths, respectively. © 2014 Wiley Periodicals, Inc.
