Abstract :
In this paper, a highly integrated direct conversion receiver MMIC for high speed E-band wireless communication is presented. The receiver consists of 3-stages LNA, doubler with buffer amplifier, and IQ-mixer. The LNA, doubler and IQ-mixer are also presented separately. The LNA covers 75 to 90 GHz with 15 dB gain and a simulated minimum 5 dB noise figure; doubler covers 75 to 90 GHz with 8 to 12 dBm output power and the IQ-mixer an RF frequency from 75 to 90 GHz and IF frequency from DC to 8 GHz with only estimated 8 dB conversion loss and better than 35 dB image reject. The complete receiver circuit shows an RF bandwidth of 75 to 90 GHz and IF bandwidth from DC to more than 8 GHz. The conversion gain is around 8 dB with a estimated noise figure of 5 to 7 dB, the image rejection 25 dB to as high as 30 dB.
