Abstract: This work presents a D-band reconfigurable Quadrature Second Harmonic modulator. The proposed modulator features a quadrature frequency doubler with integrated shunt switches at the ...

A real-time RF modulation recognition system using software-defined radio (SDR) and deep learning. Captures IQ data from RTL-SDR devices and classifies signals using a convolutional neural network ...

Abstract: This brief introduces a D-band receiver (RX) RF front-end (RFE) integrating a low-noise amplifier (LNA), a mixer, a local oscillation (LO) doubler with pre- and post-buffering stages, and an ...

The RF Report Center helps investigators stay current on the fiscal status of their sponsored awards. This analytical tool allows researchers to see integrated information from the RF business system.
