1. INTRODUCTION
1.1 OVERVIEW
7005STC-O3B-A and 7005STC-O3B-B are highly reliable and innovative Block Up-converters (BUC)
specially designed for O3B satellite communication uplink system. This equipment converts the IF
signal (7005STC-O3B-A:1052-1788 MHz, 7005STC-O3B-B: 972-1871 MHz) to RF signal (7005STC-
O3B-A: 27.652-28.388 GHz, 7005STC-O3B-B: 28.172-29.071 GHz) with maximum linear output
power of 35dBm and saturated output power of 37dBm.
This manual provides the instructions necessary for operation and maintenance of 7005STC-O3B-A
and 7005STC-O3B-B. All user interfaces present in the BUC, as well as an exact description of the
diverse signals in the connectors of the BUC, will be described in this document. This manual also
explains the RS-232 and Ethernet communication interfaces for 7005STC-O3B-A and 7005STC-
O3B-B.
1.2 GENERAL DESCRIPTION
7005STC-O3B-A and 7005STC-O3B-B are comprised of IF, LO, Up-Converter, SSPA, and DC M&C as
shown Fig. 1.

1.2.1 IF unit
IF unit amplifies the transmission signal from a remote modem and delivers it to the up-converter unit.
1.2.2 LO unit
LO unit generates two local signals to drive two LO ports of the up-converter using double conversion
structure.
1.2.3 Up-converter unit
Up-Converter converts the IF signal (7005STC-O3B-A:1052-1788 MHz, 7005STC-O3B-B: 972-1871 MHz)
to RF signal (7005STC-O3B-A: 27.652-28.388 GHz, 7005STC-O3B-B: 28.172-29.071 GHz) and also
filters out unwanted spurious and harmonics in front of SSPA. The BUC uses a double-conversion
technology to achieve better performance and cost-effective design.
1.2.4 SSPA unit
The main function of SSPA is to boost up the transmit power of the input signal to an expected level.
1.2.5 DC M&C unit
This board includes a DC/DC converter, regulators, and a EMI/EMC filter to make all kinds of DC voltages
required in the BUC. It also contains a Monitor and Control (M&C) function to monitor and control the
BUC, and communicate with a remote modem unit. The key parts for the M&C function are a
microprocessor and communication ICs for RS-232 and Ethernet.
1.3 IMPORTANT PRECAUTIONS
Read all the following instructions prior to using the BUC.
1.3.1 Reading Introduction
There is a potential safety risk unless appropriate precautions are taken while working with the BUC. All
the precaution and danger notes must be carefully read before using the BUC.
1.3.2 ESD Protection
The BUC contains elements sensitive to electrostatic discharges (ESD). It is important that the staff is
ground- connected while they are working with them.
1.3.3 Washing
Do not use liquid washing products or aerosols. Only use a damp cloth for cleaning.
1.3.4 Water and Humidity
Do not expose the BUC to standing water. Failure to follow this precaution could result in electric shock
and injury to persons.

1.3.5 Installation of the BUC
The BUC described in this manual should not be installed in an unstable situation because it may
cause serious injuries to the staff as well as a severe damage to the BUC.
1.3.6 Power Supply
An external power supply is necessary to convert the input AC 230V to +48V DC, and the internal
DC/DC converter within the BUC generates appropriate DC voltages for IF, LO, Up-converter, SSPA,
and DC M&C units.
1.3.7 Equipment Working Conditions
Never perform maintenance or make adjustments to the BUC when the power supply is connected.
1.3.8 Important Safety Information
Read the chapters on Installation and System Operation before attempting to switch on the BUC.
Do not connect the power port to a power source until all the other connections have been made.
Precautions
1.Do not operate the BUC without a cable or a RF load connected to the RF OUTPUT waveguide port.
2.Never look into the waveguide opening when the BUC is powered on.

4.INSTALLATION
This section of the manual is intended to provide aid in BUC installation.
4.1 UNPACKING
Perform an initial inspection upon receiving the BUC. You are advised to ensure the following:
•Check that the shipping container is not opened or damaged.
Have a representative from the shipping company present if you suspect that the
shipment is damaged or tempered with before opening the container.
•Check that all items in the packing list are present and undamaged.
•If any loss or damage is discovered, contact Norsat or a local representative before
proceeding.
•The shipping container and packing materials should be retained for possible reshipment.
Accessories for 7005STC-O3B-A or 7005STC-O3B-B are four waveguide adapter fixing screws,
an O-ring for the waveguide adapter.
4.2 INSTALLATION ON ANTENNA
7005STC-O3B-A and 7005STC-O3B-B have two M4 threaded holes at each side of BUC as shown
in Fig. 6 and these holes are used to fix the mounting bracket when used as stand-alone unit.
Please fix proper brackets to four fixing holes on the BUC before mounting the BUC to the antenna.
One of these fixing holes can be used to connect the BUC housing to the earth for grounding.
