Abstract :
The eightfold-band differential SiGe HBT amplifier has been demonstrated at L-band. It has been clearly shown that a concurrent multiple-band matching can be achieved with the use of the stacked LC-tank circuits. This is the first time to realize a concurrent multi-band matching of greater than dual-band. It can be expected that these results greatly contribute to the current multi-band and multi-mode communication systems as well as the next generation, adaptive and/or reconfigurable wireless radios.
