Modifies Power Good threshold for forward power. The Power Good rate is a percent of equipment rated power (500W for PJ500C-LCD, 700W for PJ700C-LCD and 1000 W for PJ1000-LIGHT), not of forward output power. This means that this threshold set at 50% will give 250, 350 and 500 W, respectively, regardless of set power level.

Power amplifier supply unit: provides adequate power supply for RF power amplifier modules. It is a switching power supply unit with PFC full range; for details of the PFC and converter modules, please see chapters 8.1.2 and 8.1.3,...
8.1.3 Switching power supply (PSL2403-03 and PSL5034) The switching power supply incorporated in this amplifier feeds 50 VDC to the RF power modules with 25 A maximum current for PJ500C-LCD and PJ700C-LCD and 34 A maximum for PJ1000light. This module has a control input that enables output voltage reduction when needed (for instance, in the event of RF output power reduction).
Wilkinson splitter and combiner using strip-line technology. Each RF module of the PJ500C-LCD (code SL010RF1002) provides 300 W rated power - which rise up to 350 W each for the PJ700C-LCD and PJ1000light RF modules (code SL010RF2002) - using a single active element built using MOS technology.
PJ500C-LCD, PJ700C-LCD & PJ1000light A directional coupler is provided at filter output to measure forward and reflected RF output power; power readings are relayed to the Interface and Bias boards to enable processing and display. The LPF board incorporates an RF output (having a level about -60 dB lower than output level) which is brought to a BNC connector (figure 6.2).
