GIRD Digital Radio

GIRD Systems’ Digital Radio (GDR) is a flexible, reconfigurable, multi-channel Software Defined Radio (SDR) with powerful high-speed signal processing resources. The GDR is built around a core single board module that can be configured to satisfy a broad range of requirements for both embedded and stand-alone systems. The GDR covers a wide frequency range and can be configured to operate with one or two independent full or half duplex transceivers in single channel or MIMO configurations.

Want a rapid custom solution?

Easily configurable stand-alone GDR for your application

• Programmable I/O to control remote auxiliary equipment
• User-selectable control and data interfaces via interchangeable front panels
• User-selectable power supply
• GIRD customizable RF Front End (RFFE) with TX power amplifier, switched harmonic filters, RX LNA and tunable cosite filters

Establish robust communications links to your requirements

• Multi-band frequency coverage (70 MHz to 6 GHz)
• Wideband operation (0.2 MHz to 56 MHz)
• Powerful signal processing architecture hosts multiple legacy and advanced emerging waveforms

Powerful signal processing meets your demands

• Scalable FPGA Resources: Zynq 7000 Series SoC
• Mezzanine for additional Kintex/Ultrascale FPGA expansion
• Multiple high-speed interfaces for remote signal processing and user data

• Advanced Communications
• MIMO
• Electronic Warfare
• Direction Finding
• Embedded
• Stand-Alone

The short answer – both! The GDR provides all of the flexibility and control of a development kit, but you can additionally seamlessly move into lab and field testing with the GDR as a stand-alone communications device. The SCA compliant architecture helps ensure that your code will be portable to your final product, if you or your customer requires a different hardware solution in your application.

Because the GDR is an SDR, many of the specifications are subject to the particular waveforms and software installed. Given its modular design, different RF board interfaces can be developed to satisfy each customer needs. However, the specifications below provide a sense of the unit’s capabilities.
