A BIDIRECTIONAL TRANSCEIVER USING A COMPACT DPDT SWITCH FOR Q-BAND PHASE ARRAY SYSTEM

摘要

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.
