1 INTRODUCTION
OVERVIEW
1.1
7010STC-O3b-A and 7010STC-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 (7010STC-O3b-A:1052-1788 MHz, 7010STC-O3b-B: 972-1871 MHz) to RF signal (7010STCO3b-A: 27.652-28.388 GHz, 7010STC-O3b-B: 28.172-29.071 GHz) with maximum linear output
power of 38dBm and saturated output power of 40dBm.
This manual provides the instructions necessary for operation and maintenance of 7010STC-O3b-A
and -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 RS232 and Ethernet communication interfaces for 7010STC-O3b-A and 7010STC-O3b-B.
FEATURES
1.2
7010STC-O3b-A and 7010STC-O3b-B are comprised of IF, LO, Up-Converter, SSPA, and DC M&C
as shown Fig. 1.

IF unit
1.2.1
IF unit amplifies the transmission signal from a remote modem and delivers it to the Up-converter
unit.
LO unit
1.2.2
LO unit generates two local signals to drive two LO ports of the up-converter using double
conversion structure.
Up-converter unit
1.2.3
Up-Converter converts the IF signal (7010STC-O3b-A:1052-1788 MHz, 7010STC-O3b-B: 972-1871
MHz) to RF signal (7010STC-O3b-A: 27.652-28.388 GHz, 7010STC-O3b-B: 28.172-29.071 GHz)
and also filters out unwanted spurious and harmonics in front of SSPA. The BUC uses a doubleconversion technology to achieve better performance and cost-effective design.
SSPA unit
1.2.4
The main function of SSPA is to boost up the transmit power of the input signal to an expected level.
The SSPA includes the following modules: Divider, Power Amplifiers, and Combiner.

DC M&C Unit
1.2.5
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.
CAUTIONS AND WARNINGS
1.3
Read all the following instructions prior to using the BUC.
Introduction
1.3.1
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 beginning to use the BUC.
ESD Protection
1.3.2
The BUC contains elements sensitive to electrostatic discharges (ESD). It is important that the staff
is ground-connected while they are working with them.
Cleaning
1.3.3
Do not use liquid washing products or aerosols. Only use a damp cloth for cleaning.
Water
1.3.4
Do not expose the BUC to standing water. Failure to follow this precaution could result in electric
shock and injury to persons.
Installation of the BUC
1.3.5
The BUC described in this manual should not be installed in an unstable situation because it may
cause serious injuries to persons as well as a severe damage to the BUC.
Power Supply
1.3.6
An external power supply is necessary to convert the input AC to +48V DC, and for the internal
DC/DC converter within the BUC to generate appropriate DC voltages for IF, LO, Up-converter,
SSPA, and DC M&C units.

Equipment Working Conditions
1.3.7
Never perform maintenance or make adjustments to the BUC when the power supply is connected.
Important Safety Information
1.3.8
Read the chapters on Installation and System Operation before powering up the BUC.
Do not connect the AC INPUT (prime power) port to a power source until all the other connections
have been made.
Waveguide
1.3.9
Never operate the BUC without a cable or RF load connected to the RF OUTPUT waveguide.
Never stand in front of or look into the waveguide during BUC operations.
