TIMTER™ Transmitters

Quasonix TIMTER™ transmitter

Third-Generation Workhorse

Quasonix digital multi-mode telemetry transmitters are the benchmark of the industry, providing unparalleled performance and value, in small, robust, power-efficient packages. The TIMTER™ transmitter, now in its third generation and smaller than ever at 4.1 cubic inches, offers the most versatility of any transmitter in the industry, with advanced capabilities like L/S/C frequency tuning and output power up to 25 Watts.

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.

Thermal Considerations

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 support@quasonix.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.
