“…The larger the gain, the wider the Table 2 summarizes the performances comparison of the present circuit with the previous published passive sub-harmonic mixers above 100 GHz based on different process. It's worth noting that as an intuitive comparison, the circuit design using the 3Lines (215 um) coupler in Figure 4 has achieved a bandwidth of 110-145 GHz [17]. Compared with previous reports, the proposed sub-harmonic mixer exhibits a good performance in terms of the operating bandwidth covering the whole D-band, the minimum area size, and FOMs.…”

“…The mixer based on active device can achieve better frequency conversion gain, but it will be accompanied by larger noise and additional DC power consumption [6,7]. The sub-harmonic mixer with diode has simple circuit structure and zero power consumption, so it is widely used in millimeter wave band [8][9][10][11][12][13][14][15][16][17]. The most typical circuit such as 78-114 GHz sub-harmonic mixer utilizes quarter-wavelength open-stub and short-stub at each end of the diodes pair to achieve good isolation between LO and RF ports, but it also brings a large chip area of 3 mm 2 [9].…”

“…Previous studies have shown that for sub-harmonic mixers using a parallel grounded APDP configuration, RF and LO are respectively connected to a common end of the diodes through two-line coupler matching networks [12], and three transmission line coupler is used firstly to simultaneously excite an RF and LO signal into the APDP for 18-40 GHz band application [23], and then extended to millimeter wave sub-harmonic mixer design above 100 GHz [17]. However, because the operating frequency and bandwidth of the transmission line are sensitive to its physical length, the coupler will directly limit the operation bandwidth of millimeter wave band and the conversion gain of the RF signal.…”

A compact broadband monolithic sub-harmonic mixer is presented in a 70 nm GaAs Technology for millimeter wave wireless communication application. The proposed mixer adopts a novel multi-line coupler structure; where the two-sided coupling energy of radio frequency (RF) and local oscillation (LO) signals are both collected and efficiently feed to anti-parallel diode pair (APDP) topology; resulting in broadband performance and compact chip size. As a comparison in the same circuit configuration; the five-line coupler can expand the bandwidth of the existing three-line coupler by 85% and reduce the area by 39.5% when the central frequency is 127 GHz. The measured conversion gain is −16.2 dB to −19.7 dB in a wide operation frequency band of 110–170 GHz. The whole chip size is 0.47 × 0.66 mm2 including test pads. The proposed mixer exhibits good figure-of-merits for D-band down-converter applications

The letter presents a high-performance doubly balanced ring mixer (DBRM) fabricated by a 0.1 µm GaAs pHEMT process that achieves ultrawide radio-frequency (RF) and intermediate frequency (IF) bandwidths. A multiple-coupled-line Marchand balun is optimized to extend the RF bandwidth. A novel structure is designed to directly extract the IF current from the RF balun without an additional IF coupler. Due to the proposed IF extraction structure, the IF bandwidth is broadened with decreased complexity. The size of the whole chip including the probe GSG pads is 0.95×0.65 mm 2 . The measured results show that the conversion loss is 7.2-11.9 dB for the RF frequency range of 35-95 GHz with an LO power level of 14 dBm and a fixed IF frequency of 1 GHz. In addition, the conversion loss is better than 12 dB for the IF frequency range from DC to 30 GHz under a fixed LO frequency. key words: ultrawide bandwidth, doubly balanced ring mixer (DBRM), Marchand balun, monolithic microwave integrated circuit (MMIC) Classification: Microwave and millimeter-wave devices, circuits, and modules
