Latest Patents

Among his latest inventions, Pepper holds patents for advanced waveguide samplers and frequency converters. His frequency converters utilize waveguides configured for local oscillator (LO), intermediate frequency (IF), and radio frequency (RF) signals to improve system performance. A notable feature of these devices is the multimode IF waveguide, designed for selectively coupling IF signals while minimizing noise from the LO signal. By employing periodically stepped waveguides or lossy conductors, the efficiency and functionality of these systems are significantly elevated.

Another significant invention is the ultrafast sampler, which incorporates a series of Schottky diodes and coplanar waveguides to create a nonlinear transmission line (NLTL). This configuration compresses a local oscillator input, generating a sequence of strobe pulses that are then capacitively coupled to sampling diodes. The system directs the sampled signals along an intermediate frequency waveguide to processing units, such as oscilloscopes, for further analysis. This intricate design allows for the differentiation between strobe pulses and signal samples, showcasing Pepper's innovative approach to signal processing.
