CHAPTER 1
DESCRIPTIONOFTHEPJRL20
1.1 GENERAL DESCRIPTION
The PJRL20 is housed in a 2U, 19" rack-mounting container comprising
a number of interconnected modules mounted internally on the bottom of
the equipment, facilitating removal and substitution.
On the front panel there are: the FWD-PWR/REF-PWR selector to select the
forward or reflected power measuring on the analog meter, the switch on
selector with its relative led and the analog meter for the measuring
of main operating parameters.
On the rear panel there are: the VDE socket for mains voltage input, the
REMOTE BNC connector to block R.F. power output from external equipment,
the R.F. Output N-type connector.
1.2 ELECTRICAL DESCRIPTION
The PJRL20 is a very high efficiency Radio Link Amplifier working
in three different frequency range : 200-780MHz, 780-890MHz, 890-970 MHz.
This equipment is a high gain Radio Link Amplifier with relatively low
input; infact, it’s typically capable of more than 20 W output power with
only 300 mW.
A voltage selector on the transformer primary allows a variety of supply
voltages to be used.
1.3 METERS AND INDICATORS
The forward and reflected power of the amplifier can be monitored
using the analog multimeter (5 Fig.1) situated on the front panel.
The power to be measured is selected by the selector (4 Fig.1).
Two red led indicators advise in case of S.W.R. alarm (1 Fig.1) and TEMP.
alarm (2 Fig.1).
The green led ON indicates the presence of the mains voltage line inside
the amplifier.
1.4 R.F. AMPLIFIER
The RF amplifier is a wide-band design and guarantees an adjustable
power output of 2 to 20 watts across the entire band.
A low-pass filter enables the PJRL20 to be used as a low power transmitter,
connected directly to an antenna.

CHAPTER 2
ELECTRICALDESCRIPTION
2.1 INTRODUCTION
This section describes, in detail, the operating theory behind the
PJRL20 amplifier. To aid understanding, the unit has been subdivided into
blocks, each of which is fully described below.
2.2 POWER SUPPLY
This circuit comprises two boards, mounted on a heat sinks, in turn
mounted at right-angles to each other on the chassis base (7 Fig.3).
The power supply generates the stabilized voltages necessary for each
of the various modules that make up the PJRL20.
After having undergone filtering for mains-borne interference, the
supply is transformed into lower voltages, rectified, smoothed and
stabilized to the following values: +12V and 2 to 15V variable.
These voltages supply the RF power amplifier. A power limiting circuit
intervenes in the event of excess SWR on the output, thus protecting the
final stage. A temperature probe, mounted on the R.F. Power Amplifier
heat-sink intervenes in the event of excess Temperature.
2.3 R.F. POWER AMPLIFIER
The final power stage is mounted on a heat sink to dissapate waste
heat and is enclosed in a totally screened, metal container, fixed to
the upper-middle part of the central section of the unit (9 Fig.3).
The R.F. signal coming from the R.F. input connector at a power level
of about 300 mW, reaches the power stage (MHW820) and is amplified to
a level of 20 W . The resultant signal is then filtered by a low-pass
filter which removes any harmonic content. A directional coupler allows
the direct and reflected power levels to be measured and displayed on
the analog voltmeter and also fedback to the power supply to check the
VSWR level.
2.4 "PJRL CONN1" CARD
This card is situated centrally on the chassis base of the equipment
(1 Fig.3). The CON-1 card receives signals coming from power supply and
send them to the front panel.

INSTALLATION
3.1 INTRODUCTION
This chapter contains the information required for installation of
the PJRL20 amplifier and for preliminary checks.
3.2 UNPACKING
Remove the unit from its packaging and before any other operation,
check for any damage that the unit may have suffered in transit and that
all front and rear panel controls are functioning.
3.3 INSTALLATION
1)
Check that the line voltage selector is correctly set for the local
supply. If not, remove the cover on which the voltages are printed
and rotate it until the required value corresponds to the arrow,
and reinsert it.
Check also that the fuse mounted inside the cover is present and
in order.
The current capacity of the fuse are as follows:
220-240 V - 3.15 A
100-120 V - 4 A
2)
Connect R.F. Output connector of a radio link transmitter (PTRLNV
or other) with the same frequency range (max. output power 1-2 W),
to R.F. Input connector of the PJRL20 (SETUP 1).
SETUP 1
3)
Connect a dummy load with a power rating of at least 20 W continuous
to the R.F. output of the amplifier, situated on the rear panel of
the unit.
It is advisable to connect a bypass wattmeter in series with this
load in order to verify the accuracy of the unit’s own internal
wattmeter.
R.V.R. Elettronica S.r.l. (Bo)
Pag. 22
PJRL20 Technical and Maintenance Manual
4)
Connect a switch, via a cable, to the INTERLOCK connector on the
rear panel so that the switch is able to short the central conductor
to its screen. Leave the switch in the short-circuit position.
5)
Verify that POWER switch of the two equipment is on the OFF position.
6)
Connect line power to the unit via the VDE socket.
N.B. It is essential that the unit be properly earthed to ensure both
the safety of the operator as well as the correct functioning of the
equipment.
7)
Switch on both the transmitter and the amplifier and check that the
green ON led is on.
Select the desired operating frequency on the transmitter.
8)
After having verified that the UNLOCK led on the transmitter is
switched off and that the unit is therefore locked to the selected
operating frequency, open the switch connected to the INTERLOCK
connector so as to remove the short circuit between the central
conductor and ground. The RF output is now enabled and should
correspond to a power level of about 20W.
To check this reading, select FWD on the meter selector and read
the power from the 50W FSD scale.
9)
If this power is not about 20W, using a small screwdriver, rotate
the ATT1 attenuator until the output power is of 20W.
Check the value with the bypass wattmeter which should be within
±10%.
10)
With the power output at 20W, select a new transmitter’s operating
frequency well away from the current value.
The UNLOCK led should switch on and the power output on the amplifier
should fall to zero at the same time. Only when the UNLOCK led
switches off on the transmitter (unit locked to new frequency)
should the power output of the amplifier resume its previous level.
11)
SWR alarm check.
Disconnect the output load and check that the S.W.R. led switches
on.
Re-connect the output load and check that REF falls to zero, the
SWR led switches off and that PWR FWD jumps to 20W.
12)
Now short circuit the central conductor of the INTERLOCK input to
ground and the output power should drop instantly to zero.
Removing the short should cause the power output to return,
gradually, to its previous level.

MAINTENANCE
4.1 SAFETY REQUIREMENTS
WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING
When the amplifier is operational, removing the top cover will
expose lethal voltages on the line voltage selector and heavy currents
on the power supply filter terminals and power transistors.
Use insulated tools for any type of maintenance work and do not touch
any internal components when the amplifier is switched on.
Ensure that the amplifier is disconnected from the line supply before
carrying out any maintenance work.
MAINTENANCE LEVEL 1
4.2 ROUTINE MAINTENANCE
The only routine maintenance required by the PJRL20 is the periodic
replacement of the cooling fan and the removal of accumulated dust.
The period between such action will depend on ambient operating
conditions such as temperature, air-borne dust levels and humidity.
It is advisable to check the unit every 6 months and to replace noisy
or worn fans. Fans should be replaced as a matter of course after no more
than 18 months of operation.

CALIBRATIONPROCEDURE
5.1 R.F. POWER AMPLIFIER MODULE CALIBRATION
After having replaced the amplifier, carry out the following
procedure (see SETUP 1):
SETUP 1
1)
Connect a bypass wattmeter between the RF output and a 50 Ohm, >20W
dummy load to verify the correct reading of the analog meter.
2)
Switch on the amplifier. Verify with voltmeter that the voltage
between the pin VPA and ground is a value from +12V to +13V; if not
adjust R23 trimmer on the power supply card.
3)
Take a reading of the output power. If this is not 20 W, adjust AT1
attenuator on the R.F. Power Amplifier module accordingly.
4)
Disconnect the dummy load from the amplifier output, check for the
lighting of the SWR indicator.
5)
Select the PWR REF reading. Adjust R1 on the PJRL CONN1 for a correct
reading (max. 2W).
6)
Reconnect the dummy load and check the output power is once more
20W.
5.2 POWER SUPPLY CALIBRATION
