|LB Modules, Serial No's 32-43, built using our Extreme BW RF Amplifier designs, are on order and being built for our customer. These modules are being deployed in a subsystem on board U.S. Navy submarines.|
|"Our experience with R. A. Wood Associates was beyond our expectations. The willingness to deliver a product in such a short time period was very refreshing. The product worked exactly as described and met our needs. We will very likely buy again." We are always pleased to hear good feedback about our products and services!|
We are currently under contract to build 109 high dynamic range
Wideband Tuners/Quad Converters over the next year. These devices
This is the improved RCT0017B Wideband Tuner/Quad Converter, which is the result of 18 months of development improvements from our original RCT0017 model.
A 2nd general purpose automated RF/Microwave Test Station was
designed and built by R. A. Wood Associates. The purpose was to
provide automated test and device characterization to:
The RF Switch/DIO Box is a custom designed LRU that provides:
We have built 5 of these for our own automated test stations. The design is universal and can be used for multiple test applications.
RPL0103 Low Frequency Wide Band RF SubAssembly features:
Great News! R. A. Wood Associates has received approval by Lockheed Martin for ISO 9001:2008 Quality Management System (2nd Party survey), and Electrostatic Discharge Control (ESD). This puts us in a better position to deliver the highest quality products to our customers. Thanks to everyone involved who helped to make this become a reality! Bob Wood
|We keep improving and adding to our lineup of available equalizer products. We currently have over 155 low loss equalizers designs with more to come. Each design is unique with a range of choices of various slopes, along with a mixture of different frequency bands from 5 kHz to 20 GHz. We can provide a selection of male and female combinations of connectors on the inputs and outputs. We'll keep updating the equalizer main page as we get more designs completed, so feel free to stop by again, or ask us if we don't have what you are looking for.|
We have officially released a new line of SimpleCycle crystal oscillators. These are temperature compenstated crystal osciillators in a very small package with +5 Volt DC in, and an SMA output connector. The key features include:
Our Wideband Down Converter and Up Converter pair offer:

We haven't posted in a while. It's because we've been crazy busy. Our newest product, the RCT0017 WB Tuner and Quad Converter, has been under development over the past 2 years, and is now available. We've designed this from the ground up to meet state of the art high input compression point, low phase noise, fast tuning speed, wide dynamic range, and wide instantaneous bandwidth requirements. A quick overview of the specifications:

We designed and built for production a 4 channel Quad Converter. Our Quad Converter design features:
This is a very complex design with very high density surface mount assemblies. Surface mount assemblies are built using pick and place machines at a contract manufacturer. Automated RF test rack, fixtures and software has been designed at R. A. Wood Associates.
|A LB RF Receiver Simulator was designed to simulate the RF front end of a submarine periscope subsystem. The noise figure, gains, and dynamic ranges were designed to simulate the actual subsystem. The amplifiers were custom designed and equalized by R. A. Wood Associates to cover a wide bandwidth from ~DC to 3 GHz. A variable attenuator allowed the output noise floor to be adjusted in 1 dB steps.|
|We celebrated the successful delivery of EDM WB Tuners/Quad Converters with a Fall Cruise in the Adirondacks. Thanks to everybody who really worked hard to help us make a high quality product with on-time deliveries to our customer!

We designed and built a 2nd (different) Automated RF Test Station
for NAVSEA NSWC, which was delivered to Crane, Indiana. This Test
Station contains many state of the art features and equipment,
We delivered a Test Station to NAVSEA Naval Surface Warfare Center (NSWC) in Crane, Indiana. The Test Station contains many state of the art features, including:
This was a very exciting project, and we really enjoyed working with our customer on this program. The complete project was delivered within 7 months of the order being placed. Great job everybody!
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.
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.
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.
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:
