Abstract :
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. This approach therefore alleviates the need for separate amplifiers for each band.
