Description
ALBA is a 3 GeV synchrotron light source located in Barcelona and operating with users since May 2012. The RF systems are based in IOT transmitters and a total of thirteen 80 kW IOT amplifiers are used to power the Storage Ring and Booster cavities at 500 MHz. A modular Solid State Power Amplifier (SSPA) has been proposed for an already designed active 3rd Harmonic RF system of the ALBA Storage Ring. This SSPA is aimed to provide up to 20 kW power per cavity in a Continuous Wave (CW) mode at 1.5 GHz nominal frequency. Accordingly, a 250 W power amplifier module, as the primary unit, has been designed and tested. This SSPA system will be composed of modules of 1 kW, combining four primary units. For these modules, a parallel combination array using a 4-way power divider/combiner of microstrip type has been designed and tested. In this poster the design of the primary unit and combination array as well as their test results will be presented.
