Mr Carlos Rosa


In 2015 BTESA manufactured its first Solid State CW RF Amplifier (SSA) for Scientific applications, applying all the good practices learnt during 20 years of designing and manufacturing amplifiers for other applications, that is, industrialized design, careful thermal management, water cooling, high redundancy, hot pluggable modules, high availability and serviceability during operation.
After that 20kWcw SSA, many other SSA projects for Scientific institutions have been implemented, in different frequencies (from 40MHz to 750MHz) and in power levels (from 200W or 600W klystron drivers, until the most recent high-power SSA of 350kW at 101MHz just delivered on July 2022 for CERN).
This presentation will highlight the technology improvements, in efficiency (from 50 to 60% wall-plug efficiency), in compacity (50kWcw in one single rack for ALBA), in LDMOS technology (from 50V to 65V) in combination techniques (from gysel or hybrid combiner to cavity combiners), etc.
