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. See the Henkel site for more information.

Is there a way for me to get a Mock-up model of a Dual TIMTER?
Thanks for your query, Gregory. One of our representatives will contact you to learn more about your use case and to determine the best possible solution for your needs.
There is no FM option into dual transmitter?
How I can define package code?
Correct, there is no FM option available on the dual transmitter. The FM option is for support of legacy systems, but the dual transmitter is designed to support modern modulations.
Package code will be defined for you once you have settled on all of the features that you want.
The dual transmitter are used with 2 antennas to improve irradiation diagram, so to improve reception data into temetery ground station.
Into dual transmitter there are some special feature to improve irradiation diagram?
the dual transmitter has some special connection with stc feature?
There is some great difference if a use 2 normal transmitter instead dual transmitter.
Here is some information that may help answer your questions. It starts with a few papers presented at the International Telemetering Conference and also includes excerpts from a couple of training presentations:
You can also do a search of our website – click the magnifying glass in the top menu and type in “STC” – to learn more about Space-Time Coding and its inclusion in Quasonix products.
