The D.T.MUX TX-MOD is a Digital Telemetry Transmitter designed to transmit airborne telemetry data from a test target to ground stations. It provides up to 10 W RF output power (up to 20W following part number) and full user-programmable in S-band / L-band and C-band following version.

The D.T.MUX TX-MOD is capable of two user-configurable modulations:
PCM-FM (ARTM Tier 0)
SOQPSK-TG (ARTM Tier 1)
User’s programmable configurations are stored in solid state nonvolatile memory.
Data and clock are received on RS422 lines up to 40 Mbps.
Monitoring is realized through an RS232 link (max baud rate = 115200bauds).
The D.T.MUX TX-MOD is designed and qualified to operate in the environmental conditions encountered during airborne missions, in pods or on board fighter aircraft, surveillance aircraft, helicopters and flight test aircraft.
