----------------------------------------------- WARNING ---------------------------------------------------
O NOT LOOK INTO THE OUTPUT PORT OF THE POWERED BLOCK UP- D
CONVERTER. Treat the powered SSPB with extreme care. Keep in mind that levels of
microwave radiation that do not induce immediate physical discomfort in most individuals can
be sufficiently high to induce longer term effects. Your eyes are particularly vulnerable parts of
your body.
The permissible levels of exposure are quite low in comparison to the power levels of the
equipment built by Advantech (e.g. less than 10 mW versus 4 to 700 W delivered by different
units). The 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. GENERAL INFORMATION
2.1 INTRODUCTION
This manual contains information that describes installation, operation and maintenance
procedures for the 125 W Ku-Band hub-mount (outdoor) Solid State Power Block Up-Converter
model SSPBM-K125-BTE. Because specialized training is required for some phases of
installation and operation, certain parts of this manual are directed only to trained personnel.
Warnings appear at the appropriate points to caution all users of potential RF and high-voltage
hazards.
For a safe and versatile operation, please read the information carefully BEFORE using the
equipment.
ADVANTECH Advanced Microwave Technologies, Inc. has prepared this manual for use as a
guide for the proper installation, operation and maintenance of ADVANTECH equipment and
computer programs. The drawings, specifications and information contained herein are property
of ADVANTECH Advanced Microwave Technologies, Inc. Any unauthorized use or disclosure of
these drawings, specifications and information is 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 Advanced Microwave
Technologies, Inc.
2.2 DESCRIPTION
The SSPBM-K125-BTE is a 125 W Ku-Band hub-mount (outdoor) Solid State Power Block Up-
Converter (SSPB). The entire SSPB is self-contained and is intended for mounting near the hub of
the antenna. It incorporates DC main power supply and forced air-cooling system, see Figure 1:
Product Outline (page 12). The block diagram of the SSPB is shown in Figure 2: Block Diagram
(page 13) and various connectors are shown in Figure 3: Connectors (page 16).
2.2.1 POWER SUPPLY
There are two power supplies in this SSPB. The power supplies provide +12 VDC high current
and a – 9 VDC low current to the Up-Converter and to the High Power Amplifier (HPA). One of
the power supplies provides +5V delivered to the RS-232 Serial Interface for Hand Held
Terminal supplying. The power supplies are configured for operation from 198-264 V AC,
single phase, 47-63 Hz.
The fan is configured for 220 VAC operation, supplied by a speed controller to allow for a
variable (temperature dependent) rotation speed.
The overall power consumption, at rated RF output power, is 1500 W.

2.2.2 UP-CONVERTER ASSEMBLY
The Up-Converter converts the input L-Band carrier into a Ku-Band carrier. The 950 – 1450 MHz
L-Band input signals are fed at the input co-axial interface connector. A block up-converter using a
low phase noise RF oscillator, which is phase locked to the 10 MHz internal reference, translates
the 950 - 1450 MHz L-Band frequency-range to 14.000 - 14.500 GHz Ku-Band frequencies. A
band-pass filter selects the appropriate up-converter term, which in turn drives a Solid State Power
Amplifier (SSPA). Integral to this module there is a variable attenuation section used for gain
control of the whole SSPB unit and a variable attenuation section used for global temperature
compensation.
2.2.3 RF DRIVER MODULE
The RF Driver Module consists of a solid state power amplifier operating over the frequency
range of 14.0 - 14.5 GHz. The driver module is integrated on a heat sink and provides an
interface for Monitor and Control Board. This module has a DC board containing the bias,
control and protection circuitry. Other feature includes Summary Alarm Indication (failure report
of one or more GaAs devices).
2.2.4 RF HIGH POWER MODULE
The RF High Power Module consists of a 125 W solid state power amplifier operating over the
frequency range of 14.0 - 14.5 GHz. A DC board containing the bias, control and protection
circuitry is included in this module. The module is integrated on a heat sink and provides an
interface for Monitor and Control board.
2.2.5 WAVEGUIDE ARM ASSEMBLY
The Waveguide Arm Assembly includes a harmonic filter, a three-port output circulator and
related power detectors (Forward and Reverse Power).
•The harmonic filter provides a minimum of 65 dB attenuation of all harmonic products other
than the fundamental signal.
•The output circulator provides one reflected power port coupled via a detector to the Monitor
and Control board for reverse power protection. The output port of the waveguide arm
assembly has a minimum 20 dB output return loss and the output flange is WR 75 (flat).
•One extra sample port, the RF Output Monitor Port, calibrated in coupling ratio versus
frequency, permits the independent monitoring of SSPA output power levels via a ‘N’ type
connector on the side panel, by using external spectrum analyzer or portable power meter.

3. INTERFACES
Each unit provide several optional
external devices. The interfaces for this model are listed b
1. Relay (Discrete) Interface: This interface offers the essential monitoring and control of the
unit by discrete signals.
2. RS-232 Interface: This interface offers the operator es itoring and control of the
unit, using a PC with Term95 or HyperTerminal comm s.
.RS-485 Interface: This interface offers the complete monitoring and control of the SSPB
Up-Converter and provides the communication and remote control through the RS-485 serial
communication port in packet mode. The system may be connected to a Monitor & Control
Panel or to a Network Manager System.
4. RF Output Monitor Interface: This interface provides a sample of the output power of the
unit through a 40dB coupler.
5. TX LED: a green/red LED indicating the state of the transmission path. If this LED is NOT
LIT, the unit is not powered (or the power supply failed). In a Redundant System, if this LED
is NOT LIT, it indicates that the unit is in STAND-BY and in MUTE state. If this LED is
RED lit, it indicates that the unit is in ALARM or in FAULT condition. If this LED is RED
FLASHING, it indicates that the unit is in MUTE state and ON-LINE (in a redundant
system).
If this LED is GREEN lit, it indicates that the unit is functioning properly. In a Redundant
system, if this LED is GREEN, it indicates that the unit is functioning properly and it is in
ON-LINE position. If this LED is GREEN FLASHING, the unit is in good functioning
condition and in STAND-BY NOT MUTE state (in a redundant system).
The LED will flash RED-GREEN when the unit is in DOWNLOAD mode.
3.1 RELAY INTERFACE
The Relay Interface uses a 10-pin circular connector mounted on the unit enclosure. The
connector type is listed in TABLE 5
s four interfaces that can be used to connect the unit to
elow:

at page 16 and the location is shown in Figure 3 at page 16.
The pin assignment for this interface is shown in TABLE 7 at page 19.
Pins A, B and C of the connector are of Form-C relay type outputs that provide for the user an
indication informing the status of the transmission path of the Up-Converter unit.
Pins G and H of the connector are inputs, allowing the user to mute or un-mute the RF path of
the SSPB Up-Converter.
CAUTION: If pin G is not connected to pin H, the transmission path will remain disabled.
