Ultimate Bitstream Accuracy Starts Here
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.
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.

Features, popular options, and specifications for Quasonix’s dual telemetry transmitters, which optionally support Low-Density Parity Check (LDPC) Coding and are Space-Time Coding (STC) capable.
It is important that the transmitter’s bottom surface (on the face opposite the product label) be securely attached to a baseplate capable of dissipating the power produced by the transmitter model in use. This mounting baseplate must be flat, smooth, and clean.
ATTENTION: You must operate the transmitter with a proper heat sink. Failure to do so may lead to permanent damage to the unit and will void the warranty. Overheating can occur in a matter of seconds when a transmitter is not properly heat-sinked. In absolutely no case should any type of stickers or labels be applied to the bottom surface of the transmitter.
The heat sink required for a particular transmitter depends heavily on the installation. Factors such as altitude, air temperature, air flow, and mass of the mounting surface all have a substantial impact on the flow of heat away from the transmitter. Quasonix offers several types of integrated and add-on heat sinks. Please contact email@example.com for the power dissipation required and heat sink recommendations for your particular TIMTER™ transmitter.
Regardless of the heat sink, Quasonix strongly suggests using a thermal pad, such as Q-Pad® II from Bergquist.
