“…As one of the essential components of RF communication front-ends, high-performance mixers are widely demanded to economically and efficiently operationalize the up/down spectrum shifting functions of signals. There are various circuit topologies and electrical configurations for mixers, which are commonly categorized into two groups, the active type [ 5 , 6 , 7 , 8 , 9 ] and passive type [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ], further classified as single-ended, single-balanced, double-balanced, triple-balanced, and subharmonic approaches. In addition, the specific selection criteria should be determined based on system specifications, including operating bandwidth, conversion loss, port isolation, and compactness [ 23 ].…”
