C-Band Transceiver 5700 series Reference Manual 2-3
Complying with the European Radio and Telecommunications T erminal
Equipment Directive
Electromagnetic comp at ibil it y
To ensure compliance with the EMC Directive is maintained, you must:
1 Use standard shielded cables supplied from Codan for all connections (see
Table 6-1 on page 6-20 for the appropriate cables).
It is not necessary to use shielded cables from the DC supply to the converter.
1 Ensure the covers for the equipment are correctly fitted.
Electrical safety
T o ensure compliance with the European Low Voltage Directive is maintained, you must
install the C-Band Transceiver 5700 series in accordance with the following safety
precautions. These precautions must be checked before applying AC power to the
transceiver.
If it is necessary to remove the covers at any stage, they must be refitted
correctly before using the equipment.
• A protective earth connection must be included in the mains wiring to the
transceiver (see page 2-6, Earth symbols).
• As the transceiver is intended for permanent connection to the mains supply,
a readily accessible switch or circuit breaker must be incorporated in the
mains wiring to enable easy isolation of the unit.
• The isolating switch must disconnect both poles simultaneously . However, if
you can positively identify the neutral conductor, you may have a single-pole
isolating device in the live conductor.
• If the unit is connected to the mains supply via a non-detachable power
supply cable, the socket-outlet must be installed near the equipment and must
be easily accessible.
• When terminating the mains supply cable to the 5582B terminal block,
ensure the protective earth wire (green/yellow) is at least 10 mm longer than
the live and neutral wires.
• Where the transceiver uses a 5582B PSU, the PSU must be set to the required
AC mains voltage and the correct fuses must be fitted (see page 6-9, Power
supply unit).
• The protective cover must be secured above the AC input terminal block.

1 Use the standard DC supply cable shown to connect the DC power to the converter:
These cables have conductors with red insulation for the +ve supply connections,
and conductors with black insulation for the –ve supply connections.
Radiation safety
R&TTE Directive 1999/5/EC article 3.1(a) specifies essential requirements for
protection of the health and safety of the user and any other person in the vicinity of an
earth station antenna. ICNIRP guidelines have been used to determine how close a
person may approach the front of the antenna without exceeding the ICNIRP general
public reference level for electromagnetic fields.
Table 2-1 specifies the minimum safe distance versus elevation angle for a 1.8 m
diameter antenna fitted with a 40 W transceiver system.
A suitable fence or other barrier must be provided to prevent casual occupancy of the
area in front of the antenna within the safe distance given in Table 2-1. As the antenna
size is increased or the transceiver output power rating is reduced, the required safe
distance becomes smaller.
PSU/SSPA Cable (Codan part number)
5582B 08-05634-xxx
5760/5712H 08-05961-xxx
Do not look into the unterminated output of the SSPA or point it towards anyone.
Always fit the correct termination to the SSPA (N-type connection or waveguide)
or fit the blanking plate (waveguide only).
Earth station antennas radiate electromagnetic fields that may be harmful to
humans. Ensure that you maintain the minimum safe distance for the elevation
angle of the antenna in your earth station (see Table 2-1).
C-Band transceiver compliance
C-Band Transceiver 5700 series Reference Manual 2-5
In the limit case, a 7.2 m diameter antenna with a 60 W transceiver system does not
require a fence or barrier.
Protection of radio spectrum
It is the responsibility of the user to ensure any modem used in conjunction with the
transceiver complies with EN 301 443 so that CE compliance with respect to radiated
spurious signals is maintained. If necessary, consult Codan for more information.
For CE compliance, the transceiver must be set up so that it does not enter the transmit
on state upon power up.

Transceiver configurations
Transceivers using a 5705/5710/5720/5730/5740 SSPA can be powered in two ways:
• the DC supply configuration, or
• the AC supply configuration with a Power Supply Unit 5582B
Transceivers using a 5760 or 5712H SSPA are powered via the AC supply connected to
the SSPA. The SSPA supplies 48 V DC to the converter.
DC supply configuration (5705/5710/5720/5730/5740 SSP As)
The DC supply configuration provides a complete transceiver system. It does not require
any indoor equipment (see Figure 3-2). Power is provided from a 48 V DC source.
AC supply configuration (5705/5710/5720/5730/5740 SSP As)
The AC supply configuration is supplied with a Power Supply Unit 5582B, which
enables the transceiver to be powered from AC mains (see Figure 3-3).
The PSU may be mounted outdoors to:
• reduce the requirement for long DC power cables
• minimise the DC power cable voltage drop
• remove the need for indoor equipment associated with the transceiver
AC supply configuration (5760/5712H SSPAs)
The 5760/5712H SSPAs can only be powered from AC mains. The power supply for the
converter in a high power configuration comes from the high power SSPAs (see
Figure 3-4).

Outdoor modules
The transceiver comprises up to five outdoor-mounting modules:
• synthesised Converter Module 5700
• Solid State Power Amplifier 5705/5710/5720/5730/5740/5760/5712H
• low noise amplifier
• transmit reject filter
• Power Supply Unit 5582B (optional, not required with 5760/5712H)
The outdoor modules of the transceiver can be mounted on the antenna or feed support
structure. Although a protected position is preferable, the modules are designed to
withstand exposure to outdoor weather conditions.
The modules are supplied with brackets and hardware to enable universal mounting.
Diagrams of significant panels and connectors for this equipment are provided in
Chapter 10, Drawings
.
Converter module
The converter performs the frequency conversion in the transceiver. It is a single,
integrated outdoor-mounted module (see drawing 03-00959 in Chapter 10, Drawings).
The converter uses dual conversion and synthesised frequency control in 1 MHz
increments. It is protected against transmitting on out-of-band frequencies.
All oscillators are phase locked to the internal reference frequency. The status of all
phase locked loops is monitored at all times. If any loop becomes unlocked, the
converter indicates a fault.
The converter also has the capability to provide automatic gain versus temperature
compensation for the SSPA. This feature is not utilised when used with the 5760 or
5712H SSPAs as they are internally compensated.
A specific feature of the up/down converter is its low spurious output specification. This
feature makes the system ideally suited to multicarrier applications.
Overview
C-Band Transceiver 5700 series Reference Manual 3-15
5705/5710/5720/5730/5740 SSPAs
The Codan C-Band transceiver is available with a 5 W, 10 W, 20 W, 30 W or 40 W low
power SSPA.
The SSPA is designed to be mounted on the feed support close to the antenna feed to
minimise transmission losses.
Each of these SSPAs has a single power output stage that provides high DC power
efficiency while maintaining excellent multicarrier intermodulation performance.
The combination of low power consumption and high speed activation from an external
control line makes the transceiver ideal for solar-powered systems.
5760/5712H SSPAs
The Codan C-Band transceiver is available with either a 60 W or 120 W high power
SSPA. These SSPA modules provide high performance together with compact size,
rugged construction and optimum thermal characteristics. Innovative RF power
combining technology, the latest GaAs FET devices and surface mount technology are
used. Remote operation of all control and status functions is possible via a serial
interface.
The SSPA modules feature an output isolator for operation into any load. Alarm
thresholds can be set for low or high power and the gain of the SSPA is adjustable over a
20 dB range. Gain variation versus temperature is automatically compensated in
firmware.
The SSPA is designed to be mounted on the antenna support structure close to the
antenna feed to minimise transmission losses.
Low noise amplifier
The LNA is mounted directly on the antenna feed Rx port. In addition to the standard
LNA, an optional higher performance LNA is available. Other LNAs may also be used.
Any LNAs used with this transceiver must receive their power via either the RF output
connector of the LNA or a separate power and alarm connector.
Transmit reject filter
The TRF is mounted directly on the antenna feed Rx port. It can be used when the
antenna feed does not provide adequate attenuation of the transmit signals at the antenna
feed Rx port.
Overview
3-16 C-Band Transceiver 5700 series Reference Manual
Power supply unit
The PSU provides DC power to the transceiver from a 50/60 Hz, 115/230 VAC source.
The PSU contains a simple transformer/rectifier supply.
The robust design of the module enables the transceiver to operate reliably when the AC
mains supply is fluctuating (see drawing 03-00993 in Chapter 10, Drawings).
Overview
C-Band Transceiver 5700 series Reference Manual 3-17
Accessories
There are two accessories available for the C-Band Transceiver 5700 series:
• the Hand-Held Controller 5560
• the Remote Controller 5570
The Hand-Held Controller 5560 is a fully-portable controller that is used to display and
change selected operating parameters of the transceiver.
The Remote Controller 5570 is a rack-mounted controller that is used to display the
operating status and change all operating parameters of the transceiver. This controller
has an in-built security function to protect the parameters of the transceiver from being
changed unintentionally or by unauthorised people.
Both controllers connect to the transceiver via the MONITOR/CONTROL connector on
the converter.
The operation of these controllers is covered in their respective user guides.

5 How the transceiver works
This chapter provides a brief technical description of the main operating components of
the transceiver. It includes the:
• converter module (5-2)
• solid state power amplifier (5-4)
• low noise amplifier (5-4)
• transmit reject filter (5-5)
• power supply unit (5-5)
How the transceiver works
5-2 C-Band Transceiver 5700 series Reference Manual
Converter module
The Converter Module 5700 provides the IF/RF frequency conversion functions required
in a C-Band satellite earth station. It consists of an up converter and a down converter.
Up converter
The up converter converts the Tx IF input signals up to the appropriate Tx RF output via
dual conversion. The actual IF frequency, IF bandwidth and RF frequency are dependent
on:
• the options fitted to the converter
• the IF selected (narrow bandwidth option only)
• the Tx frequency selected
The up converter provides a step attenuator and a gain control prior to the first frequency
conversion with the Tx LO. The gain control compensates for gain variations due to
temperature changes in both the up converter and the SSPA.
The first conversion output signal is filtered by a high-Q interdigital filter, amplified,
then applied to the second conversion stage together with the Tx synthesiser output. The
resultant signal is filtered and amplified to provide the final Tx RF output signal.
Down converter
The down converter converts the Rx RF input signals from the LNA down to the
appropriate Rx IF output via dual conversion. The actual RF frequency, IF bandwidth
and IF frequency are dependent on:
• the options fitted to the converter
• the IF selected (narrow bandwidth option only)
• the Rx (dual synthesiser) or Tx (single synthesiser) frequency selected
The Rx RF input signal is band-pass filtered and applied to the first conversion stage
together with the Rx synthesiser signal. The resultant signal is amplified and filtered
again, then applied to the second conversion stage together with the Rx LO. The second
conversion output is then further amplified and passed through the Rx step attenuator
control to provide the final Rx IF output.
How the transceiver works
C-Band Transceiver 5700 series Reference Manual 5-3
Synthesisers
The synthesisers contain two phase locked loops to produce the required SHF LO
outputs. The resolution of the frequency control is 1 MHz.
For a single synthesiser converter, the output of the synthesiser is actively split to
produce the required Tx and Rx SHF LOs. In this situation, only the transmit frequency
is programmed. The receive frequency is the transmit frequency with an offset of
2225 MHz.
All oscillators and synthesisers are phase locked to the internal reference frequency.
Control and fault detection
A microprocessor in the converter provides the control logic and fault detection for the
converter, LNA and SSPA.
The status of all phase locked loops in the converter is monitored and a converter fault is
indicated if any loop becomes unlocked. During an up converter fault period, the
converter inhibits transmission by shutting down power to the final transmit stages.
The converter monitors the supply current of the LNA to detect LNA failure and
incorporates overcurrent shutdown circuit protection.
A separate LNA DC/ALARM connector is provided on the converter. It uses a contact
closure from the LNA and current monitoring to detect failure of the LNA.
How the transceiver works
5-4 C-Band Transceiver 5700 series Reference Manual
Solid state power ampl ifier
The SSPA modules use GaAs FETs, and in the high power SSPAs, RF power combining
technology to amplify signals in the specified frequency range.
The SSPAs incorporate either a CPR137-G waveguide output or a N-type connector
output (5705/5710/5720/5730/5740 only) and an integral heatsink.
A cooling fan and shroud are fitted on all SSPAs except the 5705 SSPA. The fan operates
whenever the SSPA is activated.
In the high power SSPAs, the C-Band input signal is amplified by a variable gain driver
module, which then feeds the final power module. The final power module amplifies the
signal and divides the signal into two or four parts by a divider. In the 5760 SSPA, the
two outputs are amplified by two parallel power stages. In the 5712H SSPA, the four
outputs are amplified by four power stages. The outputs of these power stages are
combined in a waveguide power combiner.
The SSPAs are internally protected from damage in conditions of:
• overcurrent
• high temperature
• output short circuit
• output open circuit
Low noise amplifier
The LNA uses HEMT FETs to amplify signals in the specified receive frequency range.
The input is via a CPR229-G waveguide flange and connects directly to the feed to
maintain a low noise input.
Two types of LNA are recommended for operation with the C-Band Transceiver 5700
series—a standard LNA and an optional LNA. The choice is dependent on the system
requirements of the earth station.
The standard LNA has a noise temperature of 40 K and receives its DC supply via the Rx
RF cable.
The optional LNA has a noise temperature of 45 K or 35 K (depending on the version).
This LNA receives its DC supply via a separate DC/Alarm connector.
The LNA can be powered via the Rx RF I/P connector of the converter and the Rx RF
coaxial cable.
How the transceiver works
C-Band Transceiver 5700 series Reference Manual 5-5
Transmit reject filter
The TRF is a low-pass, waveguide filter. It has a low insertion loss in the specified
receive pass band and high attenuation in the specified transmit reject band.
The increased isolation between the receive and transmit ports provided by the TRF
ensures that the transmit signals will not enter and overload the LNA or down converter.
Depending upon the isolation provided by the OMT, a TRF may not be necessary on
some antennas.
Power supply unit
The Power Supply Unit 5582B is a robust, wide-range power supply. It is specifically
designed to provide the nominal 48 V DC supply required by the C-Band transceiver.
The supply source is 50/60 Hz, 115/230 VAC mains.
The PSU is unregulated and behaves like a simple transformer/rectifier supply. The DC
voltage output to the transceiver will be somewhere between 37 V (at very low mains)
and 72 V (at high mains).
The positive output of the PSU is earthed for protection. An auxiliary 48 V DC output is
provided for powering a redundancy system.
