dc.description.abstract | This study presents a 60-GHz four-element CMOS phased-array transmitter (Tx) along with a unit Tx element comprising a frequency-selective vector-sum phase shifter (VSPS), variable gain amplifier (VGA), and power amplifier (PA) in a 65-nm process. The unit Tx element with the proposed adaptive bias linearizer (ABL) delivers a measured peak gain of 25.6 dB, <italic>P</italic> <inline-formula> <tex-math notation=LaTeX>$_{\text{SAT}}$</tex-math> </inline-formula> of 11.1&#x2013;15.1 dBm, and <italic>P</italic> <inline-formula> <tex-math notation=LaTeX>$_{\text{1dB}}$</tex-math> </inline-formula> of 10&#x2013;13.2 dBm within a 3-dB bandwidth of 56&#x2013;70 GHz. The rms gain and phase error during phase shift with 11.25<inline-formula> <tex-math notation=LaTeX>$^{\circ}$</tex-math> </inline-formula> resolution are <inline-formula> <tex-math notation=LaTeX>$<$</tex-math> </inline-formula>0.37 dB and <inline-formula> <tex-math notation=LaTeX>$<$</tex-math> </inline-formula>3.2<inline-formula> <tex-math notation=LaTeX>$^{\circ}$</tex-math> </inline-formula> in the 3-dB bandwidth, respectively. Using a four-unit Tx element, the phased-array Tx is synthesized with the <italic>I</italic>/<italic>Q</italic> up-converter, providing an unwanted leakage suppression of <inline-formula> <tex-math notation=LaTeX>$>$</tex-math> </inline-formula>50 dB. For the over-the-air (OTA) test, the Tx module is assembled using the four-element phased array and a half-wave dipole antenna with a director. The Tx module provides a peak electronic gain of 45.5 dB, while delivering a <italic>P</italic> <inline-formula> <tex-math notation=LaTeX>$_{\text{SAT}}$</tex-math> </inline-formula> of 29.2&#x2013;30.8 dBm and <italic>P</italic> <inline-formula> <tex-math notation=LaTeX>$_{\text{1dB}}$</tex-math> </inline-formula> of 27.1&#x2013;28.5 dBm within a 3-dB bandwidth of 56&#x2013;68 GHz. The wireless transmission of 8-Gb/s 16-quadratic-amplitude modulation (QAM) and 4-Gb/s QPSK modulated signals was demonstrated at 1-and 4-m distances, respectively, while satisfying error vector magnitude (EVM) of <inline-formula> <tex-math notation=LaTeX>$-$</tex-math> </inline-formula>16.8 and <inline-formula> <tex-math notation=LaTeX>$-$</tex-math> </inline-formula>18.8 dB, respectively.
