SIO, August 2009

2. C-Band & Ku-Band Transceiver Systems
Overview
The C-Band Systems are labelled the 5700 series. The Ku-Band Systems are labelled the 5900 series.
Both C-Band & Ku-Band systems have four major components. Theses components are:
Power Supply
Converter Module
Solid State Power Amplifier (SSPA)
LNA (C-Band) or LNB (Ku-Band)
Power Supply – Receives AC power from the ship and converts it to 48 VDC to power the Converter & SSPA modules. The AC input is switch selectable for either 220 VAC or 110 VAC
Converter Module - The Converter Module performs multiple functions.
1. It provides the interfaces between the below decks equipment (modem & DAC) and the SSPA.
2. Power levels, attenuation levels, and frequencies are programmed in this module using either a PC or hand held controller.
3. It controls the SSPA functions and displays fault conditions.
4. It performs the frequency up conversion from 70 MHz to either C-Band or Ku-Band and the down conversion from C-Band or Ku-Band to 70 MHz

3. C-Band & Ku-Band Transceiver Systems
Solid State Power Amplifier (SSPA) – The SSPA receives DC power and the Transmit input frequency (C-Band or Ku-Band) from the Converter module. Also, any fault conditions will be relayed to the Converter where it will be displayed on the front panel window.
LNA & LNB – Provides the C-Band (LNA) or Ku-Band (LNB) signal to the Converter module for down conversion to 70 MHz.

4. C-Band & Ku-Band Transceiver Systems
Serial Communications
Monitor & Control
The Converter module is configured in two different ways. They are:
1. Remotely by connecting a PC running HyperTerminal and using the Seatel Supplied cable.
2. Directly connecting the PC to the Converter using the supplied Codan cable.
The Hyper Terminal setup communication parameters are:
9600 baud, 8 data bits, 1 stop bit , no parity, no hardware control, no flow control
The remote connection is established using the available connector (labeled “RS232”) on the interconnect cable at the back of the DAC. This cable is supplied by Seatel
The direct connection is established using the supplied Codan cable that is normally located with the Spare Parts Kit.

Typical Block Diagram for both C-Band & Ku-Band Transceiver Systems

6. Transceiver Connections - Front Panel
For Both the C-Band & Ku-Band Systems the Converter Modules have the same Front Panel Connections. These connections include:
RX IF Output (70 MHz signal to modem)
TX IF Input (70 MHz signal from modem)
Monitor & Control Connector
DC Power Input from Codan Power supply
Control Panel shows status for Power, SSPA state, and Fault conditions

7. Transceiver Connections C-Band Rear Panel
The C-Band & Ku-Band Systems Converter Modules have similar Rear Panel Connections. These connections include:
TX RF Output – Upconverted C-Band or Ku-Band signal sent to SSPA
RX RF Input Signal - LNA (C-Band) or LNB (Ku-Band)
SSPA DC voltage and control signals to amplifier
*C-Band Converter units have an LNA DC/Alarm connector. The Ku-Band Converters do not.

8. Transceiver Connections Ku-Band Rear Panel
The C-Band & Ku-Band Systems Converter Modules have similar Rear Panel Connections. These connections include:
TX RF Output - C-Band or Ku-Band signal sent to SSPA
RX RF Input Signal - LNA (C-Band or LNB Ku-Band)
SSPA DC voltage and control signals to amplifier
*Ku-Band Converters have a separate RX L-Band output. The C-Band Converters do not.
The RX L-Band Output is used mainly in combined Transmit/Receive & TVRO systems. This is the full 500 MHz receive band of the satellite

9. Transceiver Connections Front Panel Window
POWER OFF / STANDBY / ON switch When in STANDBY, only the reference oscillator and M&C sections operate. The 5700 or 5900 converter can be turned ON by the control-panel switch, a serial data command or a remote contact closure.
SSPA - INHIBIT / REMOTE / ACTIVATE The Control Panel switch allows local activation or de-activation of the SSPA for maintenance, and for re-setting alarms. Remote control is also possible by serial data command or a dry-contact closure
The highlighted switch positions correspond to: RS232 interface, ASCII protocol, 9600 bits/sec.,8 data bits, no parity.
The TERM and PACKET ADDRESS switch settings are not relevant.

11. C-Band & Ku-Band Transceiver Systems Frequency Conversions
For both the C-Band (5700) and Ku-Band (5900) Systems:
The Converter module accepts 70 MHz input from the SCPC modem (Transmit Path) which it up converts to C-Band or Ku-Band frequencies and sends to the SSPA.
The Converter module receives the C-Band or Ku-Band input from the LNA or LNB and down converts them to 70 MHz then sends them to the SCPC Modem.
The Local Oscillator (LO) for both C-Band and Ku-Band Converters is not a fixed frequency. It can be adjusted, and is selected in consideration with the satellite RF band to be covered and the frequency range of the modem.
This means that the programmed frequency of the Converter is set to the Center Frequency of the specified satellite transponder. This Center Frequency, combined with the frequency range of the modem (+/- 18 MHz) allows the modem to be tuned to a specific frequency within each 36 MHz satellite transponder.
The satellite transponder Center Frequency equals the SCPC modem Center Frequency of 70 MHz.

12. Frequency Conversion Examples - Transmit
The following example is based on a HiSeasNet Vessel operating on the Atlantic Ocean Region satellite
MHZ = Required Transmit RF Frequency as specified by satellite owner
MHz = Satellite Transponder Center Frequency – Supplied by HiSeasNet Technical Team.
Satellite Transponder Center Frequency = Modem Center Frequency of 70 MHz
AND
Difference between Transponder Center Freq +/- Assigned Freq = Difference between Modem 70 MHz +/- actual required modem frequency
Step – = MHz below modem Center Frequency
Step MHz – MHz = Required Modem Transmit IF frequency

13. Frequency Conversion Examples - Receive
The following example is based on a HiSeasNet Vessel operating on the Atlantic Ocean Region satellite
Satellite TX Frequency - Satellite Frequency Translation = Satellite RX Frequency
MHz MHz = MHz
MHZ Required Receive RF Frequency as specified by satellite owner/operator
MHz Satellite Transponder Center Frequency – Supplied by HiSeasNet Technical Team.
Step – = MHz below modem Center Frequency
Step MHz – MHz = Required Modem Transmit IF frequency
