Inthis paper, wepresent alow-power mixer withintegrated local oscillator intended foruseina24GHz receiver front-end. Thechipisrealized usingHBT GaAs technology. Thevoltage-controlled oscillator (VCO)provides atuning rangeof18%atameanfrequency of21GHz,with alowDC consumption of21mW. DC consumption ofthe mixerpartisabout17mW froma3V supply, withamean gainof14dB anda sensitivity of-70dBm.TheMMIC demonstrates interesting potential forlow-power RF termi- nalsinthe24GHzrange.
