nanoTX™ and nanoPuck™ Transmitters

Quasonix nano family of transmitters

Small Wonder

Starting at a mere 1.3 cubic inches, our nanoTx™ and nanoPuck™ transmitters support the smallest of airborne platforms with programmable multi-mode operation and up to 5 Watts of RF output. The smallest ARTM transmitters now available, Quasonix nano transmitters are ideal for applications with strict SWaP constraints.

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). (The maximum bit rate with a Clock Free transmitter is 35 Mbps for all modes.) 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.

Product Configurations

RF Output Power

  • 10 mW, 1 W, or 5 W

Frequency Band

  • Lower S band (2200.5 MHz – 2300.5 MHz)
  • Upper S band (2300.5 MHz – 2394.5 MHz)
  • Full S band

Baseband Interface

  • nanoTx™: TTL or TIA/RS-422 (RS-422)
  • nanoPuck™: LVTTL (direct connection, no cabling necessary)

Other Highlights

  • Exceptional Efficiency
  • Outputs from 10 mW to 5 W and optional variable power – all while drawing less current than the competition
  • Quasonix nano transmitters stand alone as the only 1.3 cubic inch transmitters with multi-mode and 5 W output capabilities
  • Configuration flexibility (nanoPuck™): the baseband connector can be located on either the top or bottom of the unit, as can the RF connector
  • Automatic Data Rate Tracking
  • As long as the external clock remains within the specified data rates above, the transmitter will automatically adjust to it with no programming or configuration required
  • Bypassable Randomizer
  • Standard IRIG-106 fifteen-stage randomizer, for applications with non-encrypted data
  • Intuitive Control
  • Straightforward configuration and control and platform-independence with serial terminal programming

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 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.
