“…This favors the non-isolated antenna combiner with respect to bandwidth and spectral masks requirements compared to LINCA, where only the main lobe and not the sidelobes decrease when Ψ is out-of-phase. In [8] an EVM lower than 4% within the 3 dB beam-width is obtained. Unfortunately, the power efficiency and fractional bandwidth of such a structure is not experimentally validated.…”

“…With this method coupling exists between ports 1 and 2 so that a shared current I 1,2 is maintained. In [8] it is demonstrated that such a method is feasible and behaves similar to traditional nonisolated combiners. Seen from [8], an advantage of this method can be found looking at the radiation pattern, where both the main beam and side-lobes decrease with increasing outphasing angle.…”

“…When employed in large antenna arrays needed for future base stations, these losses will impact the overall system power efficiency. That is why methods like LINC over the air (LINCA) and antenna combiners are under recent investigation [8], [9]. These methods make use of an antenna element to be co-designed with amplifiers leading to a compact, multidisciplinary and efficient system.…”

“…The author of [1], who originally introduced the concept of outphasing, intended to use non-isolated power combiners. With non-isolated power combiners, the PAs are connected to each other through the load, which in this case would be a two-port antenna such as in [4] [5] or a balun. Because the PAs are non-isolated load-modulation occurs.…”
