The SDR-U is a multi-role mesh transceiver with built-in amplifier, composed of one single board.

Designed with large-scale multi-role integration in mind, the SDR-U is rich in connectivity options including Ethernet, USB/RNDIS, RS232 / RS485 and analogue audio.

At just 15mm thick, weighing only 85g but with a full 1W of RF power, the SOL8SDR-U has the size and weight of an airborne SDR with the power of a terrestrial node.


The Heart of Integration

The SDR-U is designed to be the core of a wide range of systems. In legacy radio boards, twin 1W transceiver capability meant the use of bulky separate amplifiers, complex and fragile cabling and mounting requirements, and multiple boards vulnerable to obsolescence issues and difficult maintenance and integration. The SDR-U incorporates all the functionality of DTC's high performance Software-Defined Radios with a full 2W of output power on one single board measuring just 10mm thick.

Feature Rich

The SDR-U packs a wide range of interface options into a single board, with 7 individual connectors including RS232, Ethernet, twin USB ports, RNDIS USB, support for 3G/4G, WiFi & Bluetooth peripherals and analogue audio I/O. Able to operate both as a mesh transceiver and also unidirectional transmitter/receiver, the SDR-U supports industry-standard DVB-T as well as DTC's high performance narrowband COFDM waveform.

Industry Leading SWaP (Size, Weight & Power)

The SDR-U weighs just 85g and measures 10mm x 95mm x 60mm - the thickness of a pencil and the width of a US dollar bill.

Power Efficiency

With an input voltage range of 8 to 17.5V and consuming just 10W even in IP mesh mode, the SDR-U functions as the communications core of other platforms without costing unmanageable power overheads. Two different power input ports, including USB PD (USB-C), ensure that the SDR-U is not only efficient but easy to power from a multitude of sources.
