Ku- Band Satellite Transceiver
Introduction
1.1.2
Recommended Maintenance
The fans utilized by the KST SSPAs are designed for long life even in a harsh
environment. They are still mechanical devices subject to wear and may need
replacement after several years. Industry environments, fan shroud removal facilitates
clearing the heat sink of accumulated dust.
Once a year (or sooner depending on environmental conditions), the SSPA heat sink
should be cleaned.
To perform this maintenance:
1. Disconnect power from the SSPA
2. Remove the fan shroud assembly
3. Using compressed air, blow through the SSPA heat sink to remove
any foreign object accumulation that may be obstructing airflow.
4. Reinstall the supply and fan assembly.
No routine maintenance is required for the KST base unit.

Areas of Operation:
The areas of operation are as follows:
Converter
HPA
KST-2000A Only – Low Noise
Amplifier (LNA)
KST–2000B Only – Low Noise
Block (LNB) Assembly
FSK Remote Commands (Single-
Thread Configuration only)
Convection cooled up/down converter with an internal
power supply and microprocessor-based Monitor and
Control (M&C). The converter contains a wide band block
Ku- to L-Band down converter in the KST-2000A, or this
function may be performed in an external Low Noise
Block converter (LNB) in the KST-2000B.
Offered with various power output capabilities.
LNAs with and without a Transmit Reject Filter (TRF) and
various noise temperatures or noise figures are available.
LNBs with various frequency coverage are available.
Modifications have been made to the KST-2000A
firmware and hardware to permit monitor and control
from the front panel of select Comtech EF Data Satellite
Modems. Currently the CDM-550T and CDM-600
modems can monitor and control the KST-2000A. This
control is transmitted via an FSK signal superimposed on
the RX connection.
