Small Wonder
At a slim 1.3 cubic inches, the nanoTX™ transmitter supports 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 airborne 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

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
- 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

Does the nano-Tx support GMSK modulation?
The nanoTX™ does not explicitly support GMSK. However, GMSK and SOQPSK are both phase-shaped forms of OQPSK, and most researchers have found that the two modulations can be interchanged with only a modest mismatch loss in detection efficiency. Actual results depend on the details of the demodulator.
See this paper for a more detailed comparison: Telemetry Applications of SOQPSK and GMSK Based Modulation for Airborne Platforms
