Distributed Amplifiers in MMIC Technology based on Composite Right/Left-Handed Transmision Lines

Abstract – Three MMIC distributed amplifiers based on Composite Right/Left-Handed Transmission Lines are presented in order to illustrate the actual performance of these devices, and the features that can be obtained with this distributed amplifier topology. Measurement results and/or qualified simulations have been included for two amplifiers with dual-band performance and for a high-power one. Also different frequency bands are illustrated, with examples at X-, C- and S-band operation.Universidad de Málaga.Campus de Excelencia Internacional Andalucía Tech.
