The five RF amplifiers branches are recombined by the coupler at the output of the
amplifying modules. The overall amplified RF signal is filtered by a low-pass filter for
eliminating the harmonics and is therefore available at the output connector.
The Splitter-Coupler section is controlled by a microprocessor-based card, which
makes the values detected at the various measuring points available for the user
and for the diagnostics functions.
The machine contains five RF amplifier modules each of which is capable of supplying
a maximum of 1.2 kW RF. Each module includes a switching mode power supply unit
that regulates and stabilizes the power supply voltage supplied by the power supply
section.
Each amplifying module contains a first stage with gain that varies according to the
MOSFET BLF175. The RF signal amplified by the driver is then separated into four
branches, amplified by four modules based on BLF 278, recombined and filtered by
a low-pass filter.
Each RF amplifying module is controlled by a microprocessor-based card, connected
to the other microprocessor-based cards of the machine by means of a RS485 type
bus.
Each module runs the Automatic Power Control function for regulating the supplied
power: the gain of the amplifying stages and the voltage supplied by the switching
power supply unit are regulated so that the power that is output from the module
corresponds, if possible, to the set level.
The overall power that the PJ5KPS must supply is controlled by the microprocessor-
based card of the splitter-combiner section according to the settings made on the
control unit for the NOMINAL POWER and LOWER POWER parameters.
