3U cPCI Wideband RF-to-Digital Transceiver with Frequency Range from 200 MHz to 2.7 GHz




The RF-4902 is a wideband, frequency-agile RF-to-Digital transceiver designed to provide customers with cost-effective, high-performance RF capability in a compact 3U form factor. It features a high linearity, wideband RF tuner/exciter ranging from 200 MHz to 2.7 GHz (UHF, VHF, L-Band, ISM) for use in a wide range of applications including wideband datalinks, tactical communications, signals intelligence (SIGINT – COMINT/ELINT), and software defined radio (SDR).

Features and Benefits
  • Integrated RF and Digital IF Processing in a single 3U cPCI slot
  • High linearity, wideband RF Transceiver, 200 MHz to 2.7 GHz
  • 14-bit ADC 490 MSPS, 16-bit DAC 980 MSPS
  • Fast-frequency hopping up to 3000 hops/sec
  • Up to 170 MHz Receiver analog bandwidth
  • Up to 400 MHz Transmitter analog bandwidth
  • Xilinx Virtex-5 SX95T-2 User FPGA for flexible IF signal processing
  • High-speed serial connection to companion baseband processor
  • Software drivers and API, FPGA interface libraries, and example code included
  • Digital Down Converter (DDC) and Up Converter (DUC) IP included
  • Rugged conduction- or air-cooled form factors available
  • Designed to operate with Spectrum’s PRO-4600 baseband processing engine as part of the SDR-4000 platform
  • Not subject to US ITAR control

The SDR-4902 has an optimized noise figure. This benefits applications with weak incoming signals and low levels of interfering signals. The RF card’s RX adds very little noise to the incoming signal.

Example Applications

  • Wideband Datalinks (eg. UAV, UGV, USV)
  • Ground Mobile Communications
  • Air-to-Ground Communications
  • Communications Electronic Warfare (EW)
  • Satellite Ground Terminals
  • Cognitive Radio
  • Software Defined Radio (SDR) and Waveform Development
In a SDR-4000


Jamming App Note

Electronic Countermeasures (ECM) encompass several types of systems, one of which is a jammer. A jammer is a device that emits RF energy to disrupt sensor signals, such as RADAR, or communication signals used by an enemy. Jammer systems range from simple noise emitters, such as barrage jammers, to more sophisticated systems such as deception repeaters. A growing area of interest is the Counter-IED application that jams communication signals used to activate improvised explosive devices (IEDs).

This application note shows how a generic jammer system, a system that can be used to detect, lock onto and jam threat signals emitted by an enemy, can be implemented on its SDR-4902 system.
