SSB MMIC mixer with subharmonic LO and CPW circuitsfor 38 GHz band applications

High conversion gain cascode quadruple subharmonic mixer for millimeter-wave applications

“…In Fig. 16, the conversion gain performance of our subharmonic mixers is compared with those of the millimeter-wave subharmonic mixers reported earlier [9][10][11][12][13][14][15][16]. While the reported millimeterwave subharmonic mixers exhibited conversion gains of )15 to )7 dB, an excellent gain of 3.4 dB was obtained in this work, as shown in Fig.…”

Integrated Compact Broad Ka-Band Sub-Harmonic Single Sideband Up-Converter Mmic

“…The decreases of conversion gain at lower and higher RF frequencies are due to the insertion loss of LO short circuit at RF port of the SHP mixer. The −10 dB conversion gain at the Ka-band frequency for the sub-harmonic mixing is among the best reported values [2,5,6,8,9]. The LSB suppression is above 20 dB for 20-40 GHz.…”

“…Due to number of advantages the integrated chips become ultimate solution for the low cost and high performance transceiver systems at high frequency band. The performance of some Ka-band sub-harmonic and single sideband mixers can be found in the references [1][2][3][4][5][6][7][8][9]. Vaudescal et al have presented the integrated up-and down-converter MMICs for the customer premise equipment application at 28 GHz [10].…”

High‐conversion‐gain millimeter‐wave ×4 subharmonic mixer with cascode 4th‐harmonic generator

“…Two alternative methods to It indiffusion, proton exchange (PE) and Zn indiffusion, have been studied extensively to make optical waveguides in LiNbO 3 . They are known to be less susceptible to photorefractive damage than It:LiNbO 3 waveguide, particularly at wavelengths below 0.8 m [3,4]. Note that the PE waveguides support only the extraordinary polarization [5], whereas Zn-diffused waveguides support random or single polarization, depending upon the process parameters [6].…”
