Latest Patents

One of Brigham's latest patents is for an "Analog to Digital Converter Module and Method Thereof." This innovative module includes a plurality of frequency stacked ADCs. A splitter is utilized to divide channels into two segments, allowing the signal to be transmitted through respective low pass and high pass filters. This design enables the analog signal to be sent to both low frequency and high frequency ADCs along each channel. In a quad-tuner setup, the system can utilize eight ADCs, enhancing frequency bandwidth throughput along legacy radio frequency cables without the need for hardware replacement.

Another significant patent is the "Mezzanine Card System." This system features a baseboard designed to accommodate mezzanine cards on opposing sides. Each mezzanine card is equipped with integrated circuits, such as Field Programmable Gate Arrays. This innovative design drastically reduces reprogramming time from approximately 15 months to just six weeks, providing substantial advantages for circuitry systems, especially in battlefield and electronic warfare technology. The baseboard surfaces are finished with Electroless Nickel, Electroless Palladium, and Immersion Gold (ENEPIG) plating.
