1/4 gram NTQ

Introducing the smallest coded radio transmitter in the world: 1/4 gram NTQ

LOTEK NanoTag Series transmitters furnish researchers with a tool to collect previously unavailable data regarding movement of animals in their natural environment.

The NanoTag Series’ field-proven, energy efficient design delivers a highly stable signal, while its diminutive size and relatively long operational life enable biologists to collect data on smaller species over longer periods than ever before.

 

  • Infrared Activation and deactivation: Eliminates need for magnet removal/attachment on the transmitter during field sessions.
  • Frequency Tolerance: To ± 500Hz (DSP500 spec.). This results in stable output power at the specified frequency throughout the life of the tag.
  • Operational Range: 147MHz to 168MHz
  • Options:
    • At 0.1s burst interval increments, for more efficient use of scan times and increased detection probability.
    • Programmable for 12 hr. ON/OFF operation, to further extend operational life.
    • Also available as non-coded “beeper” transmitter.

     

At the heart of the NanoTag Series transmitter lies a technological breakthrough in microcircuitry design. NanoTag brings three distinct technologies - radio, digital processing and infrared - together on a single 2.8mm2 ASIC (Application Specific Integrated Circuit). Applying thin-thick film hybrid techniques, the ASIC and advanced surface mount components are then populated on a ceramic substrate.

NanoTag’s intended biotelemetry application meets requirements long sought within the field of fisheries research for a small and highly stable coded transmitter with a long operational life.

NanoTag series radio transmitters are primarily designed for use with Lotek digitally encoded systems. Based upon a proprietary coding scheme, our coded radio telemetry systems allow over 500 transmitters to be assigned on a single frequency, while retaining the ability to identify individual animals. This capability reduces the need for additional frequencies over conventional pulse/beeper systems, with a corresponding reduction in overall scan time. Spatial and temporal resolutions are enhanced accordingly. Burst rate/intervals selected for the NanoTag transmitter can be specified in 0.1 second increments to best meet application and operational life needs. Specifying a daily activity cycle for the transmitter further extends operational life in mobile tracking studies.
