X-Band MMIC Active Mixers [PDF]
Active and Passive Electronic Components, 2002 In this paper two active MMIC mixers for RF front-end applications are described. A down-converter that converts an RF signal (fRF=10.45 GHz) into an IF signal (fIF=0.95 GHz) using an LO signal (fLO=9.5 GHz) and an up-converter that performs the ...

77 GHz Phfet-harmonic-mixer Mmic
1997 27th European Microwave Conference, 2005 A harmonic mixer has been developed. We obtain a conversion loss of 18dB at a RF-frequency of 77GHz utilizing the 5th LO-harmonic and a LO-frequency of 15GHz (LO-power 7dBm). The mixer is a single-device gate mixer using coplanar technology and a double-heterojunction pseudomorphic HFET with 0.12?m gatelength (f1=115GHz) as active device.
