Codan C-Band & Ku-Band IF Transceiver Systems HiSeasNet Training Course SIO, August 2009

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

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.

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.

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

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

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.

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

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.

LNA & LNB Specifications Frequency range C-Band - LNA 3.400 - 4.200 GHz Ku-Band - LNB Band 1 10.95 - 11.70 GHz Band 2 11.70 - 12.20 GHz* Band 3 12.25 - 12.75 GHz Gain C-Band LNA 60 dB Ku-Band LNB 60 dB Noise temperature C-Band 50 K max Ku-Band 75 K max Note: Band 2, 11.70-12.20 GHz is the frequency band used by the HiSeasNet ships operating at Ku-Band on Satmex 5

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.

Frequency Conversion Examples - Transmit The following example is based on a HiSeasNet Vessel operating on the Atlantic Ocean Region satellite 6315.545 MHZ = Required Transmit RF Frequency as specified by satellite owner 6320.000 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 1. 6320.000 – 6315.545 = 4.455 MHz below modem Center Frequency Step 2. 70.000 MHz – 4.455 MHz = 65.545 Required Modem Transmit IF frequency

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 6320.000 MHz - 2225 MHz = 4095 MHz 4090.8525 MHZ Required Receive RF Frequency as specified by satellite owner/operator 4095.0000 MHz Satellite Transponder Center Frequency – Supplied by HiSeasNet Technical Team. Step 1. 4095.000 – 4090.8525 = 4.1475 MHz below modem Center Frequency Step 2. 70.000 MHz – 4.1475 MHz = 65.8525 Required Modem Transmit IF frequency
