A single side band(SSB) 77 GHz transmitter for radar automotive applications is presented in this paper. The direct conversion transmitter consists of a SSB sub-harmonic up-convertion mixer and a 4-stage power amplifier(PA). The 38 GHz passive coupler and balun are designed to provide IQ differential LO from external input to drive the mixer. The proposed transmitter is fabricated in 65-nm CMOS. The...
This paper describes the system architecture and design procedure for an integrated 60-GHz direct-conversion transceiver with integrated digital control interface on a 130-nm CMOS process. This transceiver incorporates both a transmitter and receiver. The transmitter achieves a Psat of 6.5 dBm, an OPldB of 1.6 dBm. The receiver achieves a conversion gain of 8.1 dB with an IIP3 of -13.74 dBm.
This paper describes the system architecture and design procedure for a 60-GHz transmitter in 130-nm CMOS process. The transmitter achieves a saturation power output of better than 4 dBm and an output-referred 1-dB compression point of 2 dBm. The LO to RF port isolation is better than 27 dB from 57 to 65 GHz. To the best of the authorspsila knowledge, this is the first reported 60-GHz transmitter...
Modern systems require transceivers that deliver gigabit speeds are smaller in size with lower power consumption and cost than existing technology consequently high speed transceivers operating at 60 GHz and delivering multi-gigabit per second are receiving significant research interest. This paper describes a 60-GHz transmitter developed and tested on a 130-nm CMOS process.
