    7 .3.1 RF Power Amplifier The RF power amplifying section consists in 8 (mod. PJ5000U-K) or 6 (mod. PJ3500M-C) power modules coupled by a Wilkinson splitter and combiner and implemented in strip-line technology. The RF modules, the splitter and the combiner are housed inside the top part of the equipment.
  • Page 40 PJ3500M-C & PJ5000U-K The splitter is used to divide input power from PWR Input Measure card and to supply a part of it to every RF module. The combiner is used to combine output power from every RF module so as to have total power amplifier.
