“…In the ideal case, the conversion gain is maximized by using a current bleeding V gs voltage of −1.3 V. Consequently, the optimal bias at an R L value of around 301.6 (ohm) is easily achieved, enabling the performance of the designed low‐LO power DBGM to be optimized. Therefore, a design tradeoff between a larger R L , determined from expectation, allows the optimization of the conversion gain of the proposed circuit .…”

A low local oscillator (LO)‐power, V‐Band MMIC down‐conversion, double‐balanced Gilbert mixer with integrated RF and LO baluns is designed and fabricated using standard 0.15‐µm pHEMT MMIC technology and characterized using probe measurements. There is a high conversion gain at a low‐LO power level. This enables the proposed “current bleeding resistor divider voltage” technique, also provided in the Gilbert‐cell mixer, to boost the conversion gain at a low–LO power level. The greatest conversion gain is from 5.17 to 1.41 dB at an RF frequency 53–60 GHz, and a Pub of −9.5 dBm at an LO input power of −7 dBm. Both RF‐LO and LO‐RF isolations are better than 25 dB. This is believed to be the lowest‐LO power and highest conversion gain so far achieved for V‐band mixers. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:60–64, 2014

“…Another advantage is that the wide frequency gap between the RF and LO signals simplifies the LO and RF separation. Frequency mixer circuits, either in microstrip [11][12][13] or in monolithic technology [14][15][16][17][18], generally use transistors [19][20][21][22][23][24], or diodes [25][26][27][28], in order to generate the desired nonlinear behavior.…”

In this work, a subharmonic frequency mixer for millimeter wave applications has been designed. The mixing and multiplication phenomena are simultaneously achieved via a nonlinear component consisting in a microstrip line gap covered by a graphene film coating. The circuit structure is made up of various filters, which have been optimized to ensure high port-to-port isolation. The nonlinear behavior of the subharmonic frequency mixer has been experimentally evaluated within the 39-40.5 GHz RF frequency band. The frequency downconversion is achieved by mixing the RF signal with the second harmonic component of a 17.9 GHz LO signal. Conversion losses are minimized by generating a return path for IF, through the use of a quarter wavelength open-ended stub.

“…Millimeter-wave and submillimeter-wave frequency multipliers [1][2][3][4][5][6] and mixers [7][8][9][10][11][12][13][14] based on planar Schottky diodes are widely used for atmosphere and space detection. The multipliers are usually driven by an oscillator [15][16][17][18] or a phase-locked millimeter-wave source.…”

Abstract-We propose a balanced frequency tripler scheme for millimeter-wave and submillimeter-wave application, in which doublesided suspended stripline is adopted. Two arms of Schottky diodes are mounted on the upper side of the substrate, and the other two arms of diodes are mounted on the lower side. The diodes are DC biased without bypass chip capacitor, which is essential in the common used balanced tripler scheme. Furthermore, the numbers of the diodes are doubled as there are only two arms of diodes in the common balanced tripler scheme, and this will double the power handling capability of the tripler. A W-band frequency tripler is designed according to the proposed scheme with commercial Schottky Varistors. The output power is from 2.9 to 5.7 dBm at the frequencies from 89.7 to 94.8 GHz, with the conversion efficiency from 1.95% ∼ 3.7%.
