Export Regulations

Under the Arms Export Control Act (AECA), 22 U.S.C. § 2778 (1994), the United
States Department of State, Directorate of Defense Trade Controls (DDTC),
implements the International Traffic In Arm Regulations (ITAR), 22 C.F.R.

§§ 120-130, which control the export of defense articles and services from the United
States to foreign destinations and persons.

Terrasat X-band IBUC products are subject to ITAR regulations administered by the
U.S. State Department. Section 121.1 of the ITAR is the United States Munitions List
(USML) and includes the commodities, related technical data, and defense services
controlled for export purposes. The X-band IBUC is classified as USML Category
XI(a)(5) “Command, control and communications systems to include radios
(transceivers), navigation, and identification equipment.” As indicated in the ITAR,

1-6 | Introduction

items in this category are also designated “Significant Military Equipment (SME).”
These products are not considered dual use as defined by the U.S. Commerce
Department.

As ITAR-controlled items that are designated SME, each license application must be
accompanied by Form DSP-83 identifying the end user and intermediate consignees.
In addition, Exporters must ascertain the specific end user and end use prior to
submitting a license application to the Directorate of Defense Trade Controls. Terrasat
normally requests a separate letter to accompany the DSP-83 stating the type of
terminal in which the IBUC will be used and the satellite system over which it will
transmit.

Further, it is required that we inform the end user of the requirements of ITAR section

123.9, as follows:

The written approval of the Directorate of Defense Trade Controls must
be obtained before reselling, transferring, transshipping, or disposing of a
defense article to any end user, end use, or destination other than as stated
on the export license.

ESCRIPTION

The Terrasat outdoor unit (ODU) consists of an intelligent block upconverter
(IBUC 2), power supply unit (PSUI), and low-noise block converter (LNB) for use in
satellite earth stations. The outdoor equipment is designed to interface directly with an
L-band satellite modem.

Introduction

This chapter contains detailed information about the various components of the
IBUC 2 system.

System Components

The interfacility link (IFL) between the ODUs and the L-band modem uses
950 MHz to 2.0 GHz (L-band) as the interface frequency. This approach enables
transmission and reception over the entire satellite band as opposed to a single
transponder. The L-band IFL can also carry associated signals such as 10 MHz, DC
voltage, or FSK which simplify installation and reduce costs. Terrasat IBUC 2 systems
can be used for single channel per carrier/multiple channels per carrier (SCPC/
MCPC), point-to-point, or point-to-multiple point network applications (such as voice,
data, video, or IP services). The integrated RJ-45 J4 connector enables TelNet, SNMP,
and the embedded Web pages for monitor and control purposes. Its smaller form factor
and lighter weight make the IBUC 2 ideal for situations where mobility is key. The
IBUC 2 can be carried in a backpack or case or it can be mounted on antennas that can
be quickly assembled and disassembled. See

Figure 2.5 to Figure 2.7 on the following

pages for typical equipment configurations.

The IBUC 2 is available in a variety of frequency bands as shown in

Table 2.1 on

page 2-3. The IBUC 2 houses the IF interface (de-mux), the upconverter, the monitor

and control (M&C) card, a DC-to-DC converter (if DC powered) and associated
circuitry, an AC-to-DC converter (if AC powered), and a solid state power amplifier

2-2 | Functional Description

(SSPA) assembly. The IBUC 2 can also house an optional internal 10 MHz reference
signal module. Higher-power IBUC 2s also have an external cooling fan assembly.
The input interface to the IBUC 2 connects to a 50 " or an optional 75 " coaxial cable
that carries the L-band transmit signal, and can carry the external 10 MHz reference
oscillator signal, DC power, and bidirectional M&C FSK signals.

DC Supply

DC power can be supplied through the N-connector or F-connector (labeled J1) of the
L-band input or through the external power connector (labeled J3). DC power for the
high-power units is supplied through the six-pin circular connector (labeled J3) of the
DC input. Higher-power units (such as Ku-band 20 watt and higher, C-band 40 watt
and higher, X-band 25 watt and higher, or DBS-band 10 watt and higher) cannot
accept DC input through the L-band input connector due to the higher current draw.

Terrasat IBUC 2s have several supply voltage options. The standard configuration is
48 VDC. However, a 24 VDC option is available for for lower power units. Refer to
the datasheets in

Appendix G for more information. This choice of 24 VDC or

48 VDC is available only when the IBUC 2 is ordered and configured at the factory.
The operating voltage range for the 24 VDC option is 20 VDC to 28 VDC. The
operating voltage range for lower-power units with 48 VDC is 37 VDC to 60 VDC.
DC-powered units are configured at the factory to have floating input.

For IBUC 2s that require fuses up to 6.3 A, Terrasat recommends time lag fuses with a
high I2t value.

For IBUC 2s that require fuses greater than 6.3 A, Terrasat recommends time lag
fuses.

For reference, the IBUC 2s are delivered with Littelfuse 213 Series fuses (surge
withstand, time lag for up to 6.3 A) or 218 Series fuses (time lag for greater than

6.3 A).

Table 2.4 explains the fuse marking schema.

Monitor and Control

The IBUC 2 is equipped with extensive monitor and control (M&C) capabilities. Use
any of the following methods to access those capabilities:

• Via the M&C 19-pin circular connector (J2) utilizing two-wire RS485. This
method requires that a separate cable must be run and connected to J2.

• Via the J2 connector using RS232. This method requires that a separate cable must
be run and connected to J2.

Figure G.1 on page G-2 contains a drawing for fabricating your own cable.

• Via the J4 connector using TCP/IP. This method requires a separate Ethernet
cable.

Figure G.2 on page G-3 contains a drawing for fabricating your own cable.

• Via the J2 connector using an optional hand-held terminal. The hand-held terminal
has its own cable.

• Via the L-band input N-connector or F-connector (J1) utilizing frequency shift
keying (FSK). Using this method requires no additional cable(s) but does require
that the FSK be multiplexed onto the L-band cable.

Note:

Some modem manufacturers offer built-in FSK capabilities for communicating with
the IBUC 2 through the L-band IFL. Refer to the modem manufacturer’s
documentation for more information.

RF Signal Flow

L-band input to the IBUC 2 is through the input N-connector or the F-connector
(labeled J1). Required inputs include an L-band signal at -20 dBm or less and a
10 MHz sine wave reference signal between +5 dBm and -12 dBm (for those units that
do not have the optional internal 10 MHz reference signal). The internal 10 MHz
reference signal meets the minimum phase noise requirements listed in

Table 2.5.

Note:

If an external 10 MHz reference signal is applied to a unit with the optional internal
10 MHz reference signal, the external signal has priority. When the external signal is
removed from such units, the system automatically reverts to the internal 10 MHz
signal, requiring no additional user input.

Input to the IBUC 2 also includes AC or DC voltage (via the J3 connector) and DC
voltage for low-power units and an FSK signal via the J1 connector. The input
(L-band, FSK, 10 MHz, and DC via coaxial cable) is routed to the demultiplexer
circuitry where the various signals are split off and routed to the appropriate circuits
within the IBUC 2 . (Only IBUC 2s with direct DC or AC via the J3 connector feed
the power supply directly.) The input voltage from the demultiplexer circuitry is
routed to the power supply and the FSK signal is routed to the M&C card.

The external 10 MHz reference signal is routed to the multiplier circuitry where its
level is first detected and an alarm issued if the signal is low. However, if the signal
level is low and the system is equipped with the optional internal 10 MHz signal, the
system will automatically switch to the internal 10 MHz signal. The 10 MHz signal is
then multiplied to the frequency used for phase-locking purposes. The output of the
multiplier is routed to the phase detector circuitry where it is compared with the phase
of the DRO (dielectric resonator oscillator) signal sample and consequently generates
a voltage that is applied as a control voltage to the DRO to adjust its frequency. The
DRO has been optimized for phase noise at a single frequency based on the frequency
band of that particular IBUC 2 . The output of the DRO is amplified and routed to the
mixer.

The L-band signal that is split off in the demultiplexer circuitry is first filtered and a
sample of it detected for input power detection and control purposes. The signal is then
amplified, and goes through a variable attenuator. The attenuation is used to provide
an attenuation adjustment of 30 dB in 0.1 dB steps and to provide automatic level
control (ALC) or automatic gain control (AGC).

After additional amplification and filtering, the signal is routed to the mixer. The
L-band signal is then mixed with the DRO signal to “upconvert” to the appropriate RF
signal based on the frequency band of the IBUC 2 . The RF signal is filtered,
amplified, and then routed to the temperature compensation circuitry. The temperature
compensation circuitry has been calibrated so that the IBUC 2 gain does not vary more
than 3 dB at any given frequency.

Note:

Some units can vary up to 4 dB at any given frequency.

The signal is then routed through an isolator to the solid-state power amplifier (SSPA).
Some models have an additional mechanical filter between the isolator and the SSPA.
The SSPA amplifies the signal which is then routed to the output through an isolator
for reverse power protection. The RF output is detected for M&C purposes. The
IBUC 2 gain has been calibrated so that at minimum attenuation, a -30 dBm input
results in rated power of at least P1dB at the output at any frequency or temperature.

Note:

Ka-band BUC 2 rated power is measured at P

SAT

.

To operate at lower power levels, reduce the input to the IBUC 2 or reduce the IBUC 2
gain by using the variable attenuator, accessible using any of the M&C interfaces. The
output of a C-band IBUC 2 is a CPR137G waveguide or an N-type connector, the
output of an X-band is a CPR112G waveguide, the output of a Ku-band IBUC 2 is a
WR75 cover with groove waveguide, the output of a DBS-band IBUC 2 is a
WR62 UG cover with groove waveguide, and the output of a Ka-band IBUC 2 is a
WR28 UG cover with groove waveguide.
