Introduction High-Power TWTA Satellite Terminals
1.1 Introduction
The key component of these high-power systems is the external high-power TWTA.
When the TWTA is coupled with the CST-5000/-7000, and KST-12000 satellite terminal
systems, these components form an integrated high-power transceiver system. These
all-weatherized units are designed for the harsh, uncontrolled, outdoor environment
typical of antenna mounting. These completely integrated systems meet the requirements
for private, regional domestic, and international C-band or Ku-band satellite networks.
All three products may be configured for single thread or 1:1 redundant systems.
Refer to Table Chapter 1-1 for a typical HPCST-5000 and -7000 redundant system.

Introduction High-Power TWTA Satellite Terminals
The system outdoor terminal components are weatherproof units for the uplink and
downlink requirements. The redundant assemblies have been designed for antenna or
pole mounting. The system has a single customer interface connector for remote monitor
and control.
The onboard microcomputer monitors and controls the operational parameters. This
M&C system enables the user to locally or remotely control functions such as:
• Output power level
• Output On/Off
• Transmit/Receive channel frequency
The system also reports terminal configuration status, as well as fault status of all
components. The RFT can be initially configured by a keyboard/LCD controller within
the enclosure, or by connection of a common ASCII/EIA-232 terminal connected to the
serial port at the system interface connector (P1). A simple command set allows
configuration control and retrieval of status information.
If the customer M&C control unit is a more sophisticated monitor and control station
computer, the serial port can be set to EIA-485 for bus operation. A separate,
rack-mounted, redundant controller for the TWTAs provides the user with control and
status of the TWTA operation, as well as an automatic high voltage enable for
switchover.
Refer to Figure Chapter 1-3 for a system block diagram of the HPCST-5000/-7000
redundant systems.
Refer to Figure 1-4 for a system block diagram of the HPKST-12000 redundant systems.

1.2 Component Descriptions
1.2.1 Low-Noise Amplifier (LNA) Assembly
A typical redundant LNA assembly consists of a transmit reject filter, waveguide switch,
and two LNAs. Optionally, a coaxial switch, 1:4 power splitter, and a block converter are
available.
For more information on the LNA assemblies, refer to the following manuals:
• CST-5000 C-Band Satellite Terminal Installation and Operation Manual
• CST-7000 C-Band Satellite Terminal (Insat) Installation and Operation Manual
• KST-12000 Ku-Band Satellite Terminal Installation and Operation Manual
1.2.2 Radio Frequency Terminal (RFT)
The RFT is a weatherproof enclosure which houses:
• Up and down converters
• Frequency synthesizer
• IF and RF interface
• M&C system
• Power supply
• Cables
In the transmit (uplink) direction, the terminal accepts a 70 MHz IF signal and transmits
it in the uplink transmit frequency band. This output is coupled through a type N
connector to the external TWTA assembly. This system provides the high-power output
to the antenna through a waveguide switch. A 40 dB coupler is included at the output of
the waveguide switch to meet INTELSAT specifications.
A high-power termination is included on the offline channel port of the waveguide
switch for testing. Each redundant thread has been factory-compensated for TX gain
stability over temperature. EFData recommends that when replacing a faulted unit, the
RFT, TWTA, and associated coax link must be replaced as a set. Otherwise, gain
stability can not be guaranteed.
In the receive (downlink) direction, the terminal accepts an RF signal in the downlink
frequency band, and down-converts it to a 70 MHz IF output. The LNA assembly has an
RF RX type N coax output to each RFT receive input.
1–6 Rev. 1
High-Power TWTA Satellite Terminals Introduction
The RFT power level at 1 dB compression to drive the external TWTA is +8 dBm. The
up and down converters are dual conversion, and are configured with individual
synthesizers for independent transmit and receive transponder selection.
For more information on RFTs, refer to the following manuals:
• CST-5000 C-Band Satellite Terminal Installation and Operation Manual
• CST-7000 C-Band Satellite Terminal (INSAT) Installation and Operation
Manual
• KST-12000 Ku-Band Satellite Terminal Installation and Operation Manual
1.2.3 TWTA Models
The TWTA is an all-weather, high-power system specifically designed for compact
outdoor installation for earth station satellite communication. Because of the
compactness, the unit can be mounted on the antenna, thus reducing transmission losses
to the antenna feed. This outdoor unit contains:
• RF filters
• Self-contained forced air cooling system
• Control inputs
• Monitor output signals
EFData offers six TWTA models that operate in the satellite earth station uplink bands.
Specific models and options are identified by the EFData part number in Table 1-3.
