ELETTRONICA

• 

Power output disabled (set to OFF) by user in FNC operation menu;  

• 

Regulated power set to 0 Watt using the edit mode;

• 

An alarm or fault condition has occurred.

  7.3.3  Power Amplifier

The RF power amplification section consists in four power modules coupled through 

a Wilkinson splitter and combiner using strip-line technology.

Each RF module provides 600 W rated power using a double active element built 

using MOS technology (SD2932). RF modules are fed by the switching power 

supply via the Bias board.

The splitter card splits the incoming power input signal equally to all RF modules. 

The combiner card combines the power output signals available at module outputs 

to obtain total amplifier power.

Splitter, amplifiers and combiner have been designed to sum amplifier output power 

signals in phase, so as to keep unbalance and power dissipation to a minimum.

The whole RF section is mounted on a finned heat sink with fan cooling.

  7.3.4  LPF Card

This  board  incorporates  a  low-pass  filter  to  keep  amplifier  harmonics  within 

permissible limits as specified by international standards.

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. This provides a convenient test 

point to check carrier characteristics, 

but does not ensure accurate assessment 

of higher harmonics

.

  7.3.5  BIAS card

The  main  purpose  of  this  board  is  to  control  and  correct  the  bias  voltage  of 

the RF amplification section MOSFETs. 

 

 

 

 

It also provides a measure of the total current drawn by the RF modules and 

incorporates a dedicated circuit for power supply fault reporting.
