Dual Telemetry Transmitter

Quasonix’ digital multi-mode dual telemetry transmitters provide the flexibility of two high performance, independent transmitters in one package. The standard 2.0 inch by 3.0 inch design includes a single MDM-15 interface as a primary connector for power, clock and data, and serial communications, while providing two separate RF outputs via SMA connectors. This configuration is ideal for two antenna applications that utilize Space-Time Coding (STC) or Frequency Diversity. The transmitters are designed to transmit airborne telemetry data from a test article to ground stations.


A legacy side by side design is employed in applications requiring bands that currently are not available in the Quasonix TIMTER Multi-mode Dual Telemetry Transmitter. A new side by side option will be available soon! For more information, contact Quasonix.

Base Configuration

ARTM Modulations

Quasonix transmitters offer three different modulations of increasing spectral efficiency - PCM/FM, SOQPSK-TG, and Multi-h CPM - also known as ARTM Tiers 0, I, and II, at standard bit rates from 0.1 to 28 Mbps (0.05 to 14 Mbps for PCM/FM). Options (HR/LR) are available to extend the upper limit to a maximum of 46 Mbps (23 Mbps for PCM/FM) and the lower limit to a minimum of 50 kbps (25 kbps for PCM/FM). With bandwidth at a growing premium in flight test telemetry, you can take advantage of 2 to 2.5 times the data capacity of the legacy PCM/FM waveform with SOQPSK-TG and Multi-h CPM.
