Densely Interleaved Arrays for Multi-Tone Transmitters
Power amplifier nonlinearities introduce unwanted spurious emissions in multi-tone antenna arrays transmitters. The focus of research is on improving the output power and linearity of such systems by means of densely interleaving several arrays together.
