A spectrum analyzer, engineer Mark Persons explains, is a marvelous tool that creates a “window” into the world of radio ...

The complaint from gamers that “there are no games to play these days” is no longer an exaggeration. As the latest blockbuster games feature movie-like graphics but disappoint with repetitive ...

Abstract: We present and fully characterize a downconverting RF-over-fiber link that uses one dual-RF drive Mach–Zehnder modulator as a phase modulator. One RF input presents the signal and the other ...

This is my version of a C64 RF Modulator replacement based on the schematics of similar designs like Zero-X/OMS's Modified Commodore RF Modulator Design and JMP$FCE2 ...

Impact Statement: This paper develops the full theory and experimentally verifies a downconverting RF photonic link that has potential to be particularly useful. The link has been described before but ...

Current technologies to modulate light in free space are bulky, slow, static, or inefficient. Now researchers have developed a compact and tunable electro-optic modulator for free space applications ...
