Software-Definable Radio Components

Silver Palm Technologies offers a series of Software-Definable Radio (SDR) products. These include highly integrated transceivers as well as supporting hardware, such as transmit/receive switches and highly linear low-noise amplifiers (LNAs) products support VITA-49 digital intermediate frequency (IF) standards, including time tagging over various industry standard interfaces. Silver Palm Technologies specializes in custom solutions should the standard product offering not meet the exact requirements.

SP-8304 Four-Channel SDR

8304The SP-8304 is a highly integrated four independent channel receiver that is ideal for mobile and fixed sight applications. Its small size allows it to be easily integrated into numerous platforms, including servers and ruggedized computers. Each receiver is fully independent, allowing the SP-8304 to be used as a powerful survey monitoring asset.

  • VITA-49-compliant digital IF
  • 9-16 VDC operation
  • 3″ x 5″ x 1″
  • IRIG-B and 1PPS support
  • Ruggedized packaging
  • PCIe interface

SP-8309 Four-Channel Transceiver

8309The SP-8309 provides four coherent receivers and one transmitter, making it perfect for direction finding for MIMO applications. The SP-8309 also supports an integrated antenna array, thus allowing for a complete system in the size of a standard computer hard drive.

  • Four channels receive, one channel transmit
  • True phase-coherent operation
  • External and internal antenna array support
  • 300 MHz to 4 GHz coverage
  • USB 3.0 interface
  • VITA-49-compliant digital IF
  • IRIG-B and 1PPS support

SP-8344 Quad 3U VPX Tuner With Digital IF Output

The SP-8344 is a modular conduction-cooled 3U VPX quad tuner. It includes four 20 MHz to 6 GHz tuners and a four-channel IF digitizer and FPGA. A 250 Msps digitizer is connected to each tuner, and the digital data from the four tuners is provided over four Aurora lanes on the VPX backplane. The unit also includes an internal GPS-stabilized, 10 MHz reference, and a 1G Ethernet interface for control.

  • Four independent tuners
  • 20 MHz to 6 GHz
  • 40 MHz bandwidth
  • VITA-49 compliant digital IF
  • Integrated GPS-stabilized reference

SP-4707 Linear Amplifier

4707_transThe SP-4707 is a high-performance amplifier specifically designed for ultralinear applications. A proprietary design yields superior second- and third-order intermodulation performance. Additionally, the unique balun configuration provides excellent phase and amplitude tracking  between amplifiers.

  • 20 MHz to 4 GHz
  • +5V single-supply operation at <350 mA
  • 13.5 dB gain typical
  • +42 dBm output IP3 typical
  • +65 dBm output IP2 typical
  • +3 dB noise figure typical

SP-4303 Intelligent Transmit/Receive

4303The SP-4303 is an intelligent transmit/receive switch that offers an enormous amount of capability and flexibility to SDR systems. The SP-4303 is designed to seamlessly integrate the antenna and power amplifier to the SDR. The switch can work autonomously or high customized by the user over a choice of standard interfaces.

  • 50 MHz to 2 GHz
  • RS-232, USB, and Ethernet interfaces
  • GPIO for system control and monitoring
  • 9-16 VDC operation
  • < 100 uSec switching time
  • Ruggedized packaging

10G Ethernet SDRs

Silver Palm Technologies has introduced a line of digital IF over 10G Ethernet products that support the next generation SDR system architecture. The products are fully VITA-49-compliant and can support either internal or external RF front-ends or can be highly customized by the user.

  • 40 MHz bandwidth at 16 bits
  • Versions with integrated RF available
  • SFP+ sites for 10G Ethernet
  • GPS-stabilized reference
  • Narrowband and wideband DDCs and resamplers
  • VITA-49 digital IF
  • IRIG-B and 1PPS support
  • Integrated front-end control and reference
  • SP-1342-1 four-channel SDR
  • SP-1381 four-to-eight channel SDR
