Available in single or dual synthesiser options, standard or extended C-Band
operation and 70 or 140 MHz IF configurations-and a range of power
outputs-the 5700 provides industry leading technical performance.
The 5700 series is designed and
tested to meet its performance
specifications in an ambient
temperature range from -40°C to
+55°C and up to 100% relative
humidity, ensuring long-term
survival in extreme conditions.
The thermal protection provided
allows operation up to +60°C
ambient. Field experience shows
that MTBFs of greater than
100,000 hours can be expected.
All user access is via a transparent
cover, which can be removed
without exposing major internal
electronics to the elements.
Special sealant is used to ensure
the sealing integrity of all
RF modules are fully sealed and
pressure tested to 34 kPa (5 psi).
Particle and moisture penetration
is rated to IP68 and the units are
submersible to 3 metres.
Internal protection against high
temperature and short or open
circuit RF output is standard. As
well, input voltage detection
ensures reliable shutdown and
restart under brownout or
Output Power Options
Output ratings of 10, 20 and
40 watts are standard, while
higher power options are also
The 5700 features a 48 V DC
floating input (37 V to 72 V range)
with reverse polarity protection.
This is ideal for battery backup
and solar-powered systems. In
addition, the 5700 may be
supplied with an optional AC
power supply unit with field
selectable 115/230 V operation.
The AC power supply unit is
extremely robust and particularly
suited for operation from poor
quality AC supplies.
RF performance is superb,

temperature and flatness across
the IF band.
The 5700 also boasts industry
leading spurious and harmonics
specifications while guaranteed
RF performance ensures
expensive system link margins do
not have to be used to cope with
RF transceiver variations. The
5700's high linearity and low

Codan's C-Band transceivers all
feature low power consumption
and low temperature rise,
ensuring internal components do
not suffer undue stress.
Enhanced Monitor & Control
All operating functions can be
controlled and monitored via the
serial interface. The operating
configuration is stored in EEPROM
to ensure the setup parameters
are restored in the event of a
Two dedicated controllers are
available from Codan:
5560 Hand-Held Controller,
suitable for in the field
5570 Remote Controller,
suitable for indoor rack
mounting to provide
permanent monitoring and
Universal Interface Compatibility
The 5700 has universal interface
compatibility capable of
operating with dumb terminals,
laptop/PC emulating terminals,
hand-held terminals and personal
organisers without requiring
proprietary software. The
versatile configuration options
support: contact closure, RS232,
RS422 and RS485 (2 or 4 wire).
Redundancy Switching System
A redundancy switching system is
available to provide an automatic
changeover to a second
transceiver to maximise link
availability and minimise any
disruption to service.
This system is fully outdoor
mounted, but can be supplied
with the 5587 Redundant System
Monitor to provide indoor
monitor and control.
