    Spectrum Control's family of software-definable, RF+ sysetm blocks work with mixed-signal devices like Direct RF FPGAs (see figure). The latest incarnation provides high-fidelity millimeter-wave (mmWave) block conversion that can down-convert wideband mmWave signals covering 18 to 40 GHz into the standard 2- to 18-GHz band. There are two input channels: 18 to 26 GHz and 26 to 40 GHz. It can support applications such as wideband RF front ends, X-Band RF front ends, frequency converters, and power amplifiers.

    Spectrum Control's RF+ SIP implements these up- and down-converter circuits.

    The SCRS-00-1001 SiP incorporates an Intel FPGA, as well as 13 voltage regulators, 11 RF amplifiers, two digital attenuators, an RF detector, and 11 RF filters. The input and output gain controls are 26 dB; gain is 22 to 28 dB. The SiP requires a 9-V DC power source. Custom configurations are available.

    I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.  

    I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
