TW-650 TSM Shadow Module

Software Defined Radio (SDR)

The TW-650 TSM Shadow Module is a software defined radio architected for embedment into a wide range of platforms for communications, network devices, and unmanned systems.

Embedded Integration

The TW-650 is a single-board radio, built for integration into custom platforms, drones, robotics, and existing systems. The radio module provides reliable connectivity for tactical mobile ad-hoc networking using TrellisWare’s TSM™ waveform. The TW-650 is ideal for applications where size, weight, and power consumption are critical.

Extensive Feature Set

The TW-650 provides a full feature set perfect for custom integration. It includes:

  • A full software API for status and control of the radio through an IP interface, and a set of Web-apps hosted on the radio for end-user configuration and monitoring of the TSM network
  • High density connectors offering flexibility in system interfaces
  • A feature set with built-in AES security and video encoding

RF Spectrum Flexibility

The TW-650 interface module has so many possibilities:

  • A single radio, not requiring any manual swap of RF modules
  • A single antenna, ideal for small UAVs where MIMO is challenging to install
  • Extended frequency coverage: UHF, L-band, and S-band
  • Configurable bandwidths ranging from 1.2 to 40 MHz
  • Audio, data, video, and positional information
