PAE T6T TRANSMITTER and T6R RECEIVER, VHF Multimode Digital Radio (MDR)
PAE
T6 Series
The PAE T6T Transmitter and T6R Receiver
for advanced airspace communications
The PAE T6T and T6R multimode digital
radios 
are designed to provide ground-to-air
communications for professional applications 
in airport and en route centres. The radios
will support both voice and ICAO defined
data modes.
The T6 series incorporates 8.33 kHz and 
25 kHz channel spacing
. The radios recognize
frequencies entered in ICAO format and
automatically adjust to the correct channel
spacing. For multichannel operation, any
combination of 8.33 kHz and 25 kHz channel
spacing can be programmed. A 100 channel
memory allows immediate recall of stored
frequencies. Front panel operation can be
‘locked’ to prevent unauthorised adjustment
of radio parameters.
The T6T supports ICAO defined offset carrier
operation. The standard master oscillator
supports two, three and four-offset carrier
operation, the optional high stability oscillator
also allows five-offset carrier operation. The
radio detects the oscillator fitted and will inhibit
five-offset carrier operation if the high stability
option is not detected.
Careful implementation of DSP techniques
significantly reduces the component count within
the radios. 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
radios 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 radios can be operated locally using the front
panel controls, or remotely via flexible control
interfaces. STANDBY mode allows the radios to be
powered on and off remotely to ensure minimal
current drain on local power supplies.
The use of innovative RF engineering allied
to sophisticated DSP technology provides
class leading performance
. The advanced
design of the T6 series transmitter and receiver
allows operation in demanding co-site conditions,
reducing the need for external filters. The T6T
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 T6R 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.  
Comprehensive Built-In Test (BIT) monitors
both static and dynamic parameters
. Results
can be viewed on the front panel LCD and
summarized via READY and ALARM indicators. All
BIT data is available for remote monitoring via serial
ports, and transmitters and receivers can be readily
networked for remote monitoring using the PAE
Multi-Access Remote Control (MARC) or similar
systems.
