|We keep working on new designs for our customers, and improving on our earlier designs. We now have over 231 equalizer designs available, more than any other manufacturer. Various slopes over frequency ranges from DC to 28 GHz are available. You can go to our Equalizer WWW page to see what we have. Actual plots are shown for each design. If you don't see what you need, let us know, and we'll see if we can help you out.|
We've recently developed the capability to automatically measure surface mount capacitors and bin them into very tight tolerance windows. We can work with 0603, 0402, and 0201 size capacitors. We can provide down to 2-2.5% tolerance capacitors for values down to 0.1 pF. These parts are typically only available in very wide tolerances (up to 50%).
This capability is very useful for filter designs, and other microwave circuit designs.
These tight tolerance capacitors can reduce or eliminate tuning typically needed to meet performance requirements.
We are going to start providing these parts to customers on a trial basis. If you are interested, please contact us to see how we can help you out!
We delivered a new design to one of our customers: An 8X8 Microwave

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 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've released some new equalizer designs in the past few months:

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!
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.
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:
More information is available from our Extreme BW RF Amplifier page. Let us know if you are interested in this product line! Bob Wood.
We've delivered another RF Receiver simulator to one of our
customers. This unit simulates the RF front end characterisitcs
(noise figure, gain, dynamic range) of an EW system, so the customer
can connect it to their back end system and validate full system end
to end performance (system sensitivity, etc), without requiring the
expensive front end components. Frequency coverage goes from 10 MHz
to 40 GHz on this unit.|
