1. SAFETY
In addition to this section, included by reference are the following pertinent sections of the
International Standard IEC-215, ‘Safety requirements for radio transmitting equipment’:
Appendix D, ‘GUIDANCE ON ASSESSING THE COMPETENCE OF PERSONNEL FOR
DESIGNATION AS SKILLED’ and also Sub-clause 3.1 of the Standard.
Appendix E, ‘GUIDANCE ON SAFETY PRECAUTIONS TO BE OBSERVED BY
PERSONNEL WORKING ON RADIO TRANSMITTING EQUIPMENT’, also Sub-clauses 3.2,
3.7 and 22.1 of the Standard.
To prevent the risk of personal injury or loss related to equipment malfunction Advantech
Wireless uses the following symbols for safety related information. For your own safety, please
read the information carefully BEFORE operating the equipment.
Symbols used in this manual:
WARNING! Indicates a hazardous procedure that may result in serious injury or death, if
not performed properly.
CAUTION! Indicates a dangerous procedure that may result in light-to-severe injury or loss
related to equipment malfunction, if proper precautions are not taken.

-------------------------------------------- WARNING ---------------------------------------------
The operator cannot repair this unit. DO NOT attempt to remove the top cover or
disassemble the internal components. Only qualified service technicians should service this unit.
There is a risk of damaging the precision components.
----------------------------------------------- WARNING ------------------------------------------
ALWAYS TERMINATE THE OUTPUT WAVEGUIDE OF THE UNIT WITH AN RF LOAD
CAPABLE OF DISSIPATING FULL CW RF POWER. SIMILARLY TERMINATE THE RF
INPUT PORT TO AVOID THE POSSIBILITY OF THE UNIT BEING DRIVEN BY STRAY
LEAKAGE SIGNALS. Incorporate the terminations prior to applying prime power to the unit.
This procedure prevents self-oscillation and irradiation from and into the local environment. If
an RF source is not connected to the RF input port, the unit may go into a self-induced mode and
generate high levels of RF energy. Destruction caused by an excessive load voltage standing
wave ratio (VSWR) will void the warranty.
----------------------------------------------- WARNING -------------------------------------------
DO NOT LOOK INTO THE RF OUTPUT PORT OF THE POWERED BLOCK
UP-CONVERTER! Handle the powered SSPB with extreme care. Keep in mind that the levels
of microwave radiation, which do not induce immediate physical discomfort in most individuals,
can be sufficiently high to induce long term effects. The eyes are the most vulnerable parts of
the body.
The maximum permissible levels of exposure are quite low in comparison to the power levels
produced by the equipment built by Advantech Wireless (e.g. less than 10 mW versus 4 to 700
W delivered by the different units). The maximum permissible levels are currently being studied
by a number of organizations. In the past the U.S. Safety Code established a dosage rate of 10
mW/cm2. Currently, there is consideration being given to reducing the permissible level to
1 mW/cm2in the United States, as has been the case for several European countries.

hazards.
For a safe and versatile operation, please read the information carefully BEFORE using the
equipment.
Advantech Wireless has prepared this manual for use as a guide for the proper installation,
operation and maintenance of Advantech Wireless equipment and computer programs. The
drawings, specifications and information contained herein are the property of Advantech
Wireless. Unauthorized use or disclosure of these drawings, specifications and information is
strictly prohibited. They shall not be reproduced, copied or used in whole or in part as the basis
for manufacturing or sale of the equipment or software programs without the prior written
consent of Advantech Wireless.
2.2 DESCRIPTION
The SSPBM-CX100-CSE is a 100-Watt CX-Band hub-mount (outdoors) Solid State Power
Block Up-Converter (SSPB). The entire SSPB is self-contained and is intended for mounting on to
the antenna hub, see Figure 1: Product Outline at page 11. It incorporates an Interface Assembly,
Up-Converter Assembly, High Power Amplifier (HPA) Assembly, Power Supply Assembly and a
Main Controller Board. The block diagram of the SSPB is shown in Figure 2: Block Diagram
(page 12) and the various connectors are shown in Figure 3: Connectors (page 15).
2.2.1 POWER SUPPLY
There is only one power supply assembly in this SSPB. The power supply provides +12 V DC
high current and – 9 V DC low current for the SSPB. The power supply is configured for
operation from 100 to 264 V AC, single phase, 47-63 Hz.
The overall power consumption, at the rated RF output power, is 500 W, typical.

SSPBM-CX100-CSE
2.2.2 UP-CONVERTER ASSEMBLY
The L-Band signal arriving from a modem enters the Up-Converter Assembly through a ‘N-type’
connector, see Figure 3: Connectors (page 15). The L-Band signal (950 MHz to
1825 MHz) enters the high gain Low Noise Amplifier (LNA) and Medium Power Amplifier
(MPA) stages that boost the RF power level sufficient for the transmission through the Up-
Converter Assembly.
Integral to the UP-Converter Assembly is a variable attenuation section that maintains the overall
gain of this module constant against changes in temperature (global temperature compensation).
A temperature dependent DC voltage is sent from a temperature sensor from within the HPA
Assembly through the power conditioner board to the attenuator. The amount of attenuation is
varied with the change in the DC voltage.
The Up-Converter Assembly converts and amplifies the incoming L-Band carrier signal into a C-
Band carrier. To achieve this requirement, this assembly contains a synthesizer, a mixer, a
multiplier, two LNAs and a band-pass filter, see Figure 2: Block Diagram (page 12). For this
application, the Up-Converter requires the L-Band signal, which is sent to the mixer and the 10
MHz reference, which is fed into the synthesizer.
The synthesizer contains a phase-locked loop local oscillator (PLL LO), which is normally
phase-locked with the incoming 10 MHz reference signal. When functioning correctly, the
PLLLO generates a 4.900 GHz LO signal. The 4.900 GHz LO signal and the L-Band signal are
fed into a mixer to produce the required C-Band signal. The frequency-range provided by the
Up-Converter Assembly is from 5.850 GHz to 6.725 GHz.
The synthesizer also contains an out of lock protection circuitry that prevents frequency shifts
from occurring to the resulting C-Band signal. When the oscillator is not phase-locked, a signal
is sent to the power conditioner board within the HPA Assembly to shutdown the RF devices.
The band-pass filter removes the unwanted harmonic frequencies, allowing the C-Band signal to
pass through the HPA Assembly.

SSPBM-CX100-CSE
2.2.3 HPA ASSEMBLY
The HPA Assembly amplifies the RF signal from the Up-Converter Assembly to a power level
sufficient for transmission. Integral to this module are three HPA stages and a power conditioner
board. Other functionality includes internal power conditioning and overtemperature shutdown.
2.2.4 CONTROLLER BOARD
All of the controls, input/output communication and the decision-making, with the exception of
the critical module-level decision are performed by the micro-controller within the Up-
Converter. The Controller Board provides through the System Control interface:
• Fault detection and indication
• Forward RF power monitoring and indication (optional)
• Temperature monitoring and indication
• ON/OFF transmit switching
• Change in the unit’s address
An ALARM will be triggered when the internal temperature of the SSPB exceeds 70°C. The
SSPB will continue to operate in this condition.
A FAULT signal will be sent to the user if any one of the following occurs:
• Phase-locked loop oscillator within the synthesizer is out of lock.
• The baseplate temperature exceeds 85 °C
• Any of the RF devices fails
In case of over-temperature (>85 °C), the SSPB will automatically restart when its internal
temperature decreases to 60 °C.

3. UNPACKINGAND INSTALLATION
This Section contains instructions for the site preparation, unpacking and the installation of an
SSPB.
3.1 INITIAL INSPECTION
Inspect the shipping container for damage. If the container or cushioning material is damaged,
immediately contact the carrier that delivered the equipment and submit a damage report.
Failure to do so could invalidate all future claims.
3.2 UNPACKING
Carefully unpack and remove all of the items from the shipping container (inspect the interior of
the container for damage). Save all of the packing material until completing a visual inspection.
Verify that all of the items listed on the packing list are present. Inspect all of the items for
evidence of damage, which might have occurred during the shipment. If damage seems evident,
immediately contact the carrier that delivered the equipment and file a claim. Failure to do so
could invalidate future claims. Check the unit thoroughly for damaged or loose parts. After
completing a visual inspection, proceed to the next step.
3.3 INSTALLATION
Installation of the SSPB includes the following four phases:
• Mechanical installation
• Electrical installation
• RF connections
• Cooling considerations
3.3.1 MECHANICAL INSTALLATION
The SSPB is designed for hub-mount (outdoors) applications.
Figure 1: Product Outline at page 11 shows the overall mechanical dimensions of this SSPB.
Page 17

SSPBM-CX100-CSE
3.3.2 ELECTRICAL CONNECTIONS
E Electrical connections to the SSPB consist of the prime power AC LINE applied to the AC
Line Connector (J5). For the connector location, see Figure 3: Connectors at page 15.
Perform the electrical connections as follows:
• Using the connector provided in the shipping kit (item 5, TABLE 10 at page 36), construct
an AC Supply cable with a pin assignment as shown in TABLE 6 at page 16.
• Verify that the AC power source is turned OFF.
• Connect the SSPB to the AC power source. For the correct input voltage level refer to
TABLE 3 at page 14.
• Turn the AC power source ON.
3.3.3 RF CONNECTIONS
The following three RF connections are provided by the SSPB:
• RF input (J1) – N-Type Female, see Figure 3: Connectors at page 15. The user needs a
N-Type male connector for the interface connection.
CAUTION! Beware of the destructive pin depth of the mating connector. When installing an
RF mating connector with a destructive pin depth into an RF component connector, damage may
occur to the RF component connector. A destructive pin depth is a connector having a pin length
that is too long in respect to the reference plane of the connector. The centre pins of the
connectors used by Advantech Wireless have a precision tolerance measured in mils (1/1000
inch). The mating connectors of the various suppliers may not be of precision types.
Consequently, the centre pins of these devices may not have the proper depth.
• RF output (J7) - CPR-137 waveguide flange (grooved), see Figure 3: Connectors at page 15.
The user needs a CPR-137 flat waveguide flange.
• Attach the correct RF cable with mating connector to their corresponding connector ports on
the SSPB.
• If necessary, connect a power meter or a spectrum analyzer to the RF output monitor port
(RF MON)
• Wrap mastic tape (item 8 of TABLE 10 at page 36) around all of the SSPB connectors in
order to prevent water/humidity ingress, which may result in damage.
• Squeeze the tape tightly, ensuring that both ends of the tape have formed around the
connector and the cable.
Page 18

SSPBM-CX100-CSE
3.3.4 COOLING CONSIDERATIONS
The SSPB is forced-air cooled. The cooling fans are configured for 12 V DC operation, supplied
by the main power supply of the unit. Depending on environmental conditions, the airflow
opening may become obstructed by debris, reducing the efficiency of the cooling system.
NOTE: The cooling fans rotation speed is temperature dependent.
Inspect the unit periodically to ensure that the grill of the fans intake and all openings on the unit
are free of any obstructions. Insufficient air-cooling will significantly impact upon the SSPB
longevity.
