Multiband power amplifier for multiband wireless applications [PDF]
2002 3rd International Conference on Microwave and Millimeter Wave Technology, 2002. Proceedings. ICMMT 2002., 2003 RF sub-systems in multimode/multiband wireless communication systems need to operate on different bands that are typically narrow but sparsely separated. We show that a single-ended dual-fed distributed amplifier can operate efficiently over several sparsely separated bands.

Multiband GaNAsP quaternary alloys [PDF]
Applied Physics Letters, 2006 We have synthesized GaNxAs1−yPy alloys (x∼0.003−0.01 and y=0–0.4) using nitrogen (N) ion implantation into GaAsP epilayers followed by pulsed laser melting and rapid thermal annealing techniques. As predicted by the band anticrossing model, the incorporation of N splits the conduction band of the GaAs1−yPy substrate, and strong optical transitions from
