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.

SSPBMg-C200-BRE

-------------------------------------------- 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.

2. GENERALINFORMATION

2.1 INTRODUCTION

This manual contains information that describes the installation, operation and maintenance

procedures for the 200-Watt C-Band hub-mount (outdoor) Solid State Power Block Up-

Converter model SSPBMg-C200-BRE. Because specialized training is required for some phases

of installation and operation, certain parts of this manual are directed only to properly trained

personnel. Warnings appear at the appropriate points to caution all users of the potential RF

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 SSPBMg-C200-BRE is a 200-Watt C-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 are two power supply assemblies in this SSPB. The first power supply provides +12 V DC

high current and – 9 V DC low current for the SSPB and +12 V DC for the fans. The second

power supply provides +48 V DC for the final GaN devices in the High Power Amlifier

Assembly. The unit is configured for operation from 90 - 264 V AC, single phase, 47-63 Hz.

It has a Power Factor Correction (PFC) of 95%, minimum.

The overall power consumption is 750 W (@ PLIN RF Output Power) and 900 W (@ PSAT RF

Output Power), typical.

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

1525 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

internal 10 MHz reference provided by the 10 MHz oscillator, 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 internal 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 6.425 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.

2.2.3 10 MHZ REFERENCE OSCILLATOR

This module is used to generate a highly stable and very low phase noise 10 MHz reference

frequency with a high stability (of ±5 x 10-8 MHz/year typical), which is required by the

converter module.
