Extreme BW RF Amplifiers

We've taken a challenge and come out on top again! We've developed an Extreme BW RF Amplifier, providing ~22 dB gain, and high dynamic range (~36 dBm Third Order Output Intercept Point) over the frequency band of 5 KHz to 2 GHz. An integrated RF package of 1.9" L X 1.3" W X 0.4" H was developed for the Extreme BW RF Amplifier and also included: DC filter to suppress power supply ripple and noise An input Equalizer where you can specify the full band slope desired An output Resistive Power Divider for providing 2 equal RF outputs The input Equalizer and output Power Divider can be "zeroed out" if not needed. The input Equalizer can be used to compensate for the amplifier slope and/or passive loss slopes. We can provide a variety of RF slopes in the input Equalizer. More information is available from our Extreme BW RF Amplifier page. Let us know if you are interested in this product line! Bob Wood.

JBU RF Plate Assemblies designed and delivered for Naval Application

R. A. Wood Associates designed, built and tested and delivered 2 "JBU RF PLate" Assemblies. These RF assemblies were used 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. The exciting part for us is that this design will actually be deployed on a US Naval vessel. This is our first of several LRU's that were designed to be used on a US Naval vessel.

New "Equalizers on Demand" RF products available

Greetings! We've been very busy working on creating a new series of RF/microwave products: "Equalizers on Demand". "Equalizers on Demand" are wideband, low loss frequency equalizers made to provide a positive gain slope from the lower frequency to the upper frequency. These equalizers are designed to flatten out slope caused by long cables or other passive losses, or amplifier negative gain slopes. We have developed a wide series of equalizers with various slopes covering the following frequency bands:

• 5 KHz to 2.0 GHz
• 0.5 to 8.0 GHz
• 1.0 to 8.0 GHz
• 1.0 to 2.0 GHz
• 2.0 to 4.0 GHz
• 4.0 to 8.0 GHz
• 4.5 to 12.5 GHz

Equalizers are very important to help your system obtain the best dynamic range performance. You can use them to flatten out a negative gain slope to reduce gain tolerances/differences before going into high dynamic range amplifiers.

We're hoping this series of products create a new paradigm in RF performance. We can provide these very quickly to help correct slope in an RF path, "Equalizers on Demand" can trim RF path slopes almost as easily as attenuators can be used to adjust nominal gains.

These products were developed internally to fill a void in the RF industry. It's very difficult to quickly order a fixed slope equalizer to correct an excessive sloped RF path without waiting 10-12 weeks for delivery. Our losses at the high frequency are the lowest available in the industry. We've searched far and wide to find products with the characteristics of our products, but could not find vendors to supply them. So we bit the bullet (many bullets) and worked on these designs ourselves.

We've worked very hard to make these products easily producible. We can deliver these very quickly (typically 2-4 weeks). If you pre-order an equalizer in a certain frequency band, and then let us know what slope you need, we can most likely incorporate the slope and deliver a tested equalizer within 1-2 weeks.

We hope we can help improve your RF/Microwave system performance with these products! Bob Wood
