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...
This paper proposes a wide-band self-demodulating receiver for 60GHz ISM band applications. The proposed receiver architecture self-demodulates the OOK input signal by using injection locked oscillator and passive mixer. This simple architecture features extremely ultra-lower-power consumption and faster settling time. Implemented in Tower Jazz 180nm SiGe technology with 200GHz fT, the proposed receiver...
In this paper, a 60 GHz low power RX and TX front ends are presented. The RX has more than 19 dB of gain between 58.2 and 67.8 GHz, an average NF of 8.7 across the frequency band of interest, and a P1dB of •24.4 dBm. The high performance RX chip only consumes 32.6 mW of power, including the buffers used to drive measurement equipment. The TX employs the sliding-IF scheme with first IF at one fifth...
