Abstract
Conference Title: 2014 IEEE/MTT-S International Microwave Symposium - MTT 2014 Conference Start Date: 2014, June 1 Conference End Date: 2014, June 6 Conference Location: Tampa, FL, USA A new sub-harmonic QPSK architecture is proposed for microwave and millimeter-wave applications including transceiver. The developed 60GHz differential quadrature sub-harmonic QPSK modulator based on the proposed new QPSK architecture can not only reject both the image frequency and LO leakages but also reduce the LO operation frequency to the half of the conventional modulator. Moreover, the proposed QPSK modulator provide flexibility to select either the low sideband (LSB) or upper side band (USB) and support data rate as high as 3.52Gbps. The compact chip size is only 400um×300um and power consumption of 28mW is much smaller as compared to that of the state of the arts. [PUBLICATION ABSTRACT]
