modulation sound broadcasting, manufactured by R.V.R. Elettronica S.p.A..A control system
for the exciters is built into the machine so that in order to have a system with redundant exci-
ters, all that needs to be done is to include two exciters in the transmitter such as, for exam-
ple, the PTX30LCD exciters made by R.V.R. Elettronica S.p.A.
This manual is written as a general guide for those having previous knowledge and
experience with this kind of equipment, well conscious of the risks connected with the
operation of electrical equipment.
It is not intended to contain a complete statement of all safety rules which should be
observed by personnel in using this or other electronic equipment.
The installation, use and maintenance of this piece of equipment involve risks both for the per-
sonnel performing them and for the device itself, that shall be used only by trained personnel.
. for injury or damage resulting from improper procedures or practices by untrained/unquali-
ed personnel in the handling of this unit.
Please observe all local codes and re protection standards in the operations of this unit.
WARNING: always disconnect power before opening covers or removing any part of this unit.
Use appropriate grounding procedures to short out capacitors and high voltage points before
servicing.
WARNING: this device can irradiate radio frequency waves, and if it’s not installed following
the instructions contained in the manual and local regulations it could generate interferences
in radio communications.
In a residential place this equipment can cause hash. In this case can be requested to user to
take the necessary measures.
R.V.R. Elettronica S.p.A. reserves the right to modify the design and/or the technical
specications of the product and this manual without notice.

decided to return the unit to the factory, R.V.R. Elettronica will mail you a regular authori-
zation with all the necessary instructions to send back the goods.
When you receive the authorization, you can return the unit. Pack it carefully for the
shipment, preferably using the original packing and seal the package perfectly. The custo-
mer always assumes the risks of loss (i.e., R.V.R. is never responsible for damage or loss),
until the package reaches R.V.R. premises. For this reason, we suggest you to insure the
goods for the whole value. Shipment must be effected C.I.F. (PREPAID) to the address
specied by R.V.R.’s service manager on the authorization
DO NOT RETURN UNITS WITHOUT OUR AUTHORIZATION AS THEY WILL BE

The personnel employed in the installation, use and maintenance of the device, shall be
familiar with theory and practice of rst aid..
3.1 Treatment of electrical shocks
3.1.1 If the victim is not responsive
Follow the A-B-C’s of basic life support
• Place victim at on his back on a hard surface
• Open airway: lift up neck, push forehead back (Fig. 3-1).
• Clear out mouth if necessary and observe for breathing
• if not breathing, begin articial breathing (Figure 3-2): tilt head, pinch nostrils, make
airtight seal, four quick full breaths. Remember mouth to mouth resuscitation must be
commenced as soon as possible
• Check carotid pulse (Fig 3-3); if pulse is absent, begin articial circulation

PJ10KPS-CA
User & Technical Manual 8
Additional important features of the PJ10KPS-CA are as follows:
The amplier can work as usual even if the control unit is not present. In fact, the control
unit may be substituted temporarily with an electromechanical interface by means of which
the user may give the ON and OFF commands to the machine. However, in this case all
the numeric type information will be missing and the power level remains the last one ena-
bled before removing the control unit.
● Immediate power foldback under severe / damaging fault conditions of VSWR. The po-
wer of transmitter should automatically come down to a suitable safe design limit, so that
the transmitter and its subsystem does not get damaged due to load mis match. Details
of fold back to be provided.
●
●
● Each module is controlled by a microprocessor-based card that checks and adjusts its
operating mode. The resulting data are transmitted to the control unit.
● The 2.2 kW amplifying modules are implemented by means of plug-in technology: the
individual modules may be removed for performing maintenance operations, for instance,
without having to turn off the transmitter. The transmitter keeps working at reduced power
even if the module has been removed. This operation may be carried out without any risk
of damaging the module itself, or the amplier as a whole, thanks to the control system
and to the RF connectors, the power supply and the purposely designed data-exchange.
For further information refer to the maintenance section.
The control unit manages the changeover of the two exciters both in automatic and ma-
nual mode.
The foldback function, on the VSWR protection, works automatically on bias voltage and PA volta-
ge, reducing them to ensure that the machine can work at maximum power, not to damage internal
organs (mosfet, combiners and dummy load).

4.4 Operating principles
This description is based on the block diagram shown in Figure 4-1.
The PJ10KPS-CA amplier essentially comprises two blocks:
● The Splitter-Coupler section
● The RF amplier section
The Splitter-Coupler section performs all the treatment of the RF signal except for the power ampli-
cation.

Figure 4-1 Block diagram of PJ10KPS-CA
The RF signals generated by two exciters (in the redundant conguration) are rst attenuated by 6
dB to improve the uncoupling among the stages and then connected to a coaxial relay commanded
by the control unit. One of the two signals is closed on a dummy load built into the machine whereas
the other signal is connected to the input splitter. The power of both signals is measured by specic
directional couplers.
The RF signal of the selected exciter is divided into ve branches, each of which is passed to the
input of an amplifying module.
The ve RF ampliers branches are recombined by the coupler at the output of the amplifying modu-
les. The overall amplied RF signal is ltered by a low-pass lter 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.

PJ10KPS-CA
User & Technical Manual 10
The system contains ve RF sub-amplier modules each of which is capable of supplying a maximum
of 2.2 kW RF. Each RF sub-amplier module incorporate a PFC (Power Factor Corrector) power
supply that provides the utmost power efciency for enhanced energy savings and environmental
protection.
Each RF sub-amplier module contains a rst stage with gain that varies (driver) according to the
MOSFET BLF175. The RF signal amplied by the driver is then separated into three branches, am-
plied by three LDMOS MRF6VP11KHR5, recombined and ltered by a low-pass lter (Figure 4-2).

Each RF sub-amplier module is controlled by a microprocessor-based card, connected to the other
microprocessor-based cards of the system by means of a RS485 type bus.
Each RF sub-amplier 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 RF sub-amplier module corresponds, if possi-
ble, to the set level.
The overall power that the PJ10KPS-CA must supply is controlled by the microprocessorbased card
of the splitter-combiner section according to the settings made on the control unit for the NOMINAL
POWER and LOWER POWER parameters.
