After providing an introduction to active antenna systems (AAS) for cellular infrastructure, this paper presents power amplifier (PA) modules based on a balanced configuration of 2-8 fully integrated Doherty MMIC PAs. To our knowledge for the first time, a module with four Doherty MMIC PAs in a balanced configuration has been fabricated and tested. For a 10… (More)
extraction by Acetone, Hexane and Benzene has been evaluated. The 120 hours experimental Data were described by a simple mathematical model. According to the simulation results and the essential criteria, Acetone is superior to other solvents but under certain conditions where oil extraction takes place Hexane is superior catalyst.
