Ritron DTX LS Wireless Transceiver Data Module Board Only Version

The DTX-Ls Series wireless transceiver modules are high-performance, cost-effective, low current drain, single-board OEM transceivers available in VHF and UHF frequency bands.

High specifications permit integration into systems demanding the utmost performance in frequency congested environments. This single-board radio is available as a board-only model or installed in an extruded aluminum enclosure, both versions are FCC and Industry Canada Approved.

The DTX-Ls transceiver features all electronic tuning (no mechanical adjustments), available in 2 to 8 Watt UHF Models and 2 to 5 Watt VHF models, and supports voice or data applications and sub-audible signaling CTCSS or Digital Coded Squelch.

  • Single Printed Circuit Board
  • Programmable RF Transceiver
  • SMA Antenna Connector
  • Straight-up DB-15 Data / Power Connector
  • All electronic tuning (no mechanical adjustments)
  • Same mechanical footprint and electrical interface as the current DTX-Ls (allows drop-in backward compatibility)
  • Available in 2 to 8 Watt UHF Models and 2 to 5 Watt VHF
  • Supports voice or data applications
  • Supports sub-audible signaling CTCSS or Digital Coded Squelch
  • PC programmable via a Windows-based
  • PC programmer
  • All components are placed on the top side of a single PCB for mechanical rigidity and increased protection against damage.
  • Solid internal ground plane for enhanced EMI shielding.
  • Surface acoustic wave (SAW) filter front-end for no-drift, adjustment-free filtering off interfering signals (DTX-445).
  • Monolithic Gilbert cell mixer with internal negative feedback for improved RF intermodulation performance.
  • Ritron exclusive flex-divider PLL synthesizer allows for a wide loop bandwidth for fast transmit and receive attack times and minimal microphonics
  • Audiophile-grade polypropylene capacitors in the PLL loop filter for further reduced microphonic susceptibility.
