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 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.
The spectrum around 60 GHz is available for unlicensed operation in many regulatory domains including the USA, Japan, Canada and Australia. One of the applications of this spectrum is for short range communication systems. These systems are designed to deliver gigabit speeds, consuming small amount of power in small form factor. The small factor is achieved because passive components scale with carrier...
Modern systems require transceivers that deliver gigabit speeds, are smaller in size, and have lower power consumption and cost. This motivates research to develop transceiver-on-chip and transceiver-in-a-package technologies. Recent advances in millimetre wave electronics have meant that significant portions of the system can now be integrated onto a single substrate or package. In order to achieve...
