Abstract

An integrated frequency agile quadrature E-band receiver is presented in this paper. The complete receiver is realized in a commercial 0.35μm SiGe:C technology with an ft=fmax of 170/250GHz. The receiver covers the two point to point communication bands from 71 to 76 GHz and 81 to 86 GHz and the automotive radar band at 77 GHz. A wide tuning range modified Colpitts oscillator provides an LO tuning range > 30\%. A two stage constant phase RC polyphase network is implemented to provide wide-band quadrature (IQ) LO signals. The measured phase imbalance of the network stays below 8 over the receiver’s frequency range. In addition the chip includes a wide-band LNA, Wilkinson power divider, down conversion mixers and frequency prescaler. Each of the chip’s receiver I/Q paths shows a measured conversion gain above 19 dB and an input referred 1 dB compression point of -22 dBm. The receiver’s measured noise figure stays below 11 dB over the complete frequency range. Furthermore, the receiver has a measured IF bandwidth of 6 GHz. The complete chip including prescaler draws a current of 230mA from a 3.3V supply, and consumes a chip area of 1628μm x 1528 μm.
