An interview with Tony Long - Millimeter Microwave Magician
Tony Long, founder of Reactance Labs, discusses his work building millimeter-wave amateur radio equipment and the technical challenges of GHz frequencies. He explains the physics of atmospheric attenuation, the necessity of exotic materials like Rogers substrates and Gallium Arsenide MMICs, and the precision machining required for waveguide components. Long also details his new line of open-source hardware kits, including the OpenSynth frequency synthesizer, designed to fund his passion for high-frequency radio experimentation.
