The optional front panel display/keypad does not beep.
Change Specifics:
As incorrectly specified in Chapter 4, page 4-3:
The RFT-1225 responds by beeping whenever a key is pressed:
• A single beep indicates that the key pressed was a valid entry, and that
the appropriate action was taken.
• A double beep indicates the key pressed was an invalid entry.

This chapter describes the KST-12025 Ku-band satellite terminal, referred to in this
manual as “the KST-12025” (Figure 1-1).
1.1 Description
The KST-12025 is a 25W Ku-band satellite earth station electronics terminal configured
in two assemblies:
• The feed assembly consists of a transmit reject filter and a Low Noise Amplifier
(LNA).
Chapter 1.
INTRODUCTION
1
• The outdoor enclosure assembly (the RFT-1225) consists of a solid state power
amplifier, up and down converters, Monitor and Control (M&C) microprocessor,
and power supply.
The KST-12025 meets all requirements for operation on both private and regional
domestic Ku-band satellite networks.

Introduction KST-12025 Ku-Band Satellite Terminal
1.1.1 Applications
When used in conjunction with EFData modems, the KST-12025 terminal is ideal for:
• Single digit carriers
• Multiple carrier operation over a 36 MHz bandwidth
Because the terminal has a 70 MHz IF, it can also be used for other analog and digital
applications.
Small-to-medium size earth stations are easily constructed and commissioned with the
terminal.
When used with a high-gain antenna, the KST-12025 can also be used as the Radio
Frequency (RF) electronics of a central hub in point-to-multipoint applications, as well
as serve as the terminal for the end points of the network.
1.1.2 Monitor and Control
An on-board microcomputer monitors and controls all operational parameters and system
status of the KST-12025. This powerful M&C system enables the user to locally or
remotely control functions such as:
• Output power
• Transmit/receive channel frequencies
The system also reports terminal configuration status, as well as fault status of all
KST-12025 components.
The terminal can be initially configured by a keyboard/LCD controller within the
enclosure, or by connection of a common ASCII/RS-232 terminal connected to the serial
port. A simple command set allows total configuration control and retrieval of status
information.
If the indoor unit is a more sophisticated station monitor and control computer, the serial
port can be set to RS-485 for bus operation.
For more information on the M&C board, refer to Chapter 5.
1–4 Rev. 1
KST-12025 Ku-Band Satellite Terminal Introduction
1.1.3 LNA Assembly
The LNA assembly consists of a wave guide transmit reject filter and an LNA.
The transmit reject filter provides receive system protection from transmit energy fed
back through the antenna feed system.
The LNA standard noise temperature is 120°K, with optional upgrades down to 80°K,
depending upon gain over temperature (G/T) requirements.
1.1.4 Outdoor Enclosure
The outdoor unit (the RFT-1225) is a weatherproof enclosure housing the following:
• Solid State Power Amplifier (SSPA)
• Up and down converters
• M&C microprocessor
• Power supply and cables which interface with an antenna subsystem
In the transmit (uplink) direction, the RFT-1225 accepts a 70 MHz IF signal, and
transmits it in the 14.0 to 14.5 GHz frequency band.
In the receive (downlink) direction, depending upon the frequency band options, the
terminal accepts an RF signal in either the full 10.95 to 12.75 GHz band, or within an
individual sub-band (10.95 to 11.7 GHz, 11.7 to 12.2 GHz, 12.25 to 12.75 GHz), and
converts the signal to 70 MHz IF output.
Power level is 25W, and is temperature-compensated for maximum stability.
The up and down converters are dual conversion, with individual synthesizers for
independent transmit and receive transponder selection.
The microprocessor provides:
• Online loop monitoring
• Dynamic control functions
• Configuration control
• Fault/status monitoring
• Serial computer/terminal interface

1.2.1 Configurations
The KST-12025 can be ordered with various configurations, including:
• Output power levels
• Input power (AC/DC)
• Step sizes
• Synthesizers
• LNA gain
• Redundant LNA mounting plates
• Custom logos
Contact an EFData marketing representative for more information.
1.2.2 Equipment
The following items are available:
• KP-10 hand-held keypad. The KP-10 provides portable, external access for
controlling the RFT. For more information, refer to the EFData KP-10 External
Keypad Installation and Operation Manual.
• Front panel display/keypad. The optional front panel provides the local user
interface, which can be used to configure and monitor the status of the terminal.
For more information, refer to Chapter 4.
• High-performance low-noise amplifiers (LNAs).
