• LB Modules SN #10 and 11 Ready for Delivery!
  10/31/2009 10:24pm

  Our 10th and 11th LB RF modules, containing our Extreme BW RF amplifiers, have been built, and tested, ready for delivery to our customer. These modules will be used in our customer's systems, which will be installed on board Navy vessels.

• SpurFinder 3.5.2 Update Released
  10/6/2009 7:17pm

  We've updated SpurFinder to version 3.5.2. This update fixed a user interface bug: When the program was initially opened, the "Continuous Run/Single Run" selector was hidden from the user interface. This selector didn't reappear until the user opened a "Multi Scenario Script File" from the file menu, and then closed the file. This may have caused some confusion in using the program, which we apologize for. The update is free and can be obtained by downloading the SpurFinder installation files from our Software Download Page. Previously registered software will still be registered during the installation.

• ESSU SN3 Delivered
  10/5/2009 12:17am

  We've delivered the third Electronics Support Switching Uint (ESSU) for one of our customers (ahead of schedule!). This was another set of hardware slated to to be installed on a Navy Vessel. The ESSU is shown here with the cover removed, looking from the back. All RF components are mounted on both sides of a center RF plate. Shown are RF amplfiers, equalizers, attenuators, RF switches, cabling, FPGA card, and rear connectors (21 RF connectors, 12 video/75 ohm connectors, Audio, Power). For additional information, please visit our ESSU information page.

• R. A. Wood Associates awarded contract from NSWC Crane Division
  9/29/2009 9:19pm

  R. A. Wood Associates has been awarded a contract from Naval Surface Warfare Center (NSWC), Crane Division. The contract involves designing and delivering an automated test rack consisting of: A 40U rack with rack mount PC, work table, LCD monitor, GPIB controller cards, A state of the art Vector Network Analyzer (VNA) with 10 port extension A PXI chassis with PXI cards providing thermocouple temperature measurement, serial ports, 2 X 96 digital I/O signals A custom designed RF Load Box for testing up to eight transmitter/receiver modules, capable of providing 50 Watts of RF power Custom designed software for controlling the Load Box and the VNA equipment We are fortunate to be able to work with Viewpoint Systems on this contract. This contract was won on a competitive bid, and our solution was selected out of many other submissions. We are very excited about the opportunity to work with NSWC Crane Division!

• JBU RF Plate SN3 Delivered
  8/27/2009 8:40pm

  JBU RF Plate SN3 was delivered to our customer (ahead of schedule!). The RF Module was designed to provide wideband gain, equalization, and Built-in-test (BIT) injection between two very long RF cable runs (between an Antenna Assembly and below decks receivers). The gain and equalization was needed to preserve the RF path noise figure and dynamic range performance through the long cable run. All RF test data (gain, slope, flatness, return loss, input 1 dB compression point, and noise figure) was collected using our in house test equipment and our in house automated RF test software (Painless Extraction, Painless Extraction Noise Figure, and RFSpecTest). Mechanical parts were fabricated externally from our SolidWorks created mechanical drawings, and chem-film treated with Iridite (MIL-C-5541E Class 3) to prevent corrosion.

• RF Receiver Simuator SN4 Delivered
  8/21/2009 7:46pm

  We've delivered our fourth RF Receiver Simulator, and our 6th of a family of Receiver Simulator products. The simulators are designed to represent the RF front end (noise figure, gain compression point, and intercept point) of a complex EW system, to allow testing, verification and validation of the EW system back end, without requiring the expensive front end components. If you have a need for one of these types of products, please contact us.

• Extreme BW RF Amplifier extended to 3 GHz for Direct Laser Modulation Application
  7/8/2009 1:07pm

  We've extended the frequency range of our extreme BW RF Amplifier from 5 KHz to the upper end of 3 GHz. We customized the input equalizer to create a very flat gain response across the entire band. This amplfier was used for a direct laser modulation application. The measured performance was:

  Average Gain: 16.31 dB Slope: 0.53 dB P-P Flatness: 0.83 dB Min Gain(Low Freq): 15.30 dB Max Input Return Loss: -13.02 dB Max Output Return Loss: -9.99 dB Average 1 dB Output Comp Point: 20.7 dBm Min 1dB Output Comp Point: 19.97 dBm Noise Figure at Low Freq: ~12.8 dB Noise Figure at High Freq: ~ 5.77 dB

  More information is available from our Extreme BW RF Amplifier page. Let us know if you are interested in this product line! Bob Wood.
