The PAE T6TR TRANSCEIVER

PAE T6TR
The PAE T6TR TRANSCEIVER
for advanced airspace communications
The PAE T6TR multimode digital
transceiver for ground-to-air
communications is intended for use at
low and medium density airports and air
traffic control installations, emergency services
and airline communications. The compact
dimensions allow the T6TR to be conveniently
used for both desk and rack mount
operations. The radio supports both
voice and ICAO defined data modes.
The radio can be operated locally using the
front panel controls, or remotely via flexible
control interfaces. STANDBY mode allows
the radio to be powered on and off remotely
to ensure minimal current drain on local
power supplies. A 100 channel memory
allows immediate recall of stored frequencies.
Frequency change can be inhibited to prevent
unauthorised tuning.
Both 8.33 kHz and 25 kHz channel spacing
are incorporated. The T6TR recognises
frequencies entered in ICAO format and
automatically adjusts to the correct channel
spacing. For multichannel operation, any
combination of 8.33 kHz and 25 kHz channel
spacing can be programmed.
Careful implementation of DSP techniques
significantly reduces the component count
within the radio. This leads to increased
reliability and reduced logistic costs.
All modulation and demodulation processes
are carried out using DSP algorithms that
provide consistent long-term performance
to further enhance equipment reliability.
All adjustable parameters within the radio can
be modified using the front panel controls, or
from a computer connected to the headset/
diagnostics port, eliminating the need to
remove equipment covers during the
operational life of the radio.
The use of innovative RF engineering allied
to sophisticated DSP technology provides
class leading performance. The advanced
design of the T6TR transceiver allows operation
in demanding co-site conditions, reducing the
need for external filters. The transmitter
employs a sophisticated feedback technique that
minimizes spectral noise and enhances signal
purity. The power amplifier is designed for
optimum performance and maximum reliability
and will support continuous operation applications.
The receiver circuitry benefits from unique
DSP implemented Digital Coherent Mute
(DCM) technology. DCM uses specially
developed algorithms that monitor on-channel
activity and dynamically filter unwanted interfering
signals. The receiver front-end has exceptional
signal handling properties that ensure rejection
of unwanted off-channel signals while maintaining
excellent low level wanted signal performance.
Two antenna ports are provided allowing maximum
flexibility, these may be configured for separate
receiver and transmitter antenna connections, or
a single combined receive/transmit antenna.
The use of separate antenna ports allows the T6TR
to be used with filter multicouplers in larger
system applications. A solid state T/R switching
relay is used to provide both long-term reliability
and the high speed necessary for VDL modes.
Comprehensive Built-In Test (BIT) monitors
both static and dynamic parameters.
Results can be viewed on the front panel
LCD and summarised via READY and ALARM
indicators. All BIT data is available for remote
monitoring via serial ports and transceivers
can be readily networked for remote monitoring
using the PAE Multi-Access Remote Control
(MARC) or similar systems.
