Radio frequency tech is everywhere, from the phones in our pockets to the satellites above us. Spanning from mere kilohertz to tens of terahertz, the RF spectrum powers communication, sensing, navigation, and even the unglamorous but essential tools that heat, seal, and sanitize products worldwide. Because RF applications are so diverse, the expertise required is just as broad. Together with Mouser Electronics, we have launched a new series titled “Mastering RF Engineering”. The series examines

All radio frequency (RF), microwave, mmWave, and terahertz systems rely on a single critical component: the antenna. Poor antenna design or selection can render a system non-functional or unsafe, even if all other components are high-quality. Often treated separately from system design, antennas may be added late or outsourced, sometimes sacrificing performance for versatility. Optimizing an antenna requires considering system goals, materials, environment, and regulatory compliance, making it a

🔧 The Physical Engines of HAARP HAARP (High-frequency Active Auroral Research Program) operates as a high-power ionospheric heater. It uses radio frequency (RF) transmissions to excite targeted regions of the ionosphere. Core Machinery: 1. Diesel Generators or Natural Gas Turbines • Provide the raw power (often megawatts) necessary to operate the system. • The HAARP site in Gakona, Alaska was originally powered by 5 powerful diesel generators, each producing around 3.6 MW. 2. Transmitters • A b
