RF Engineering Across the Spectrum: Fundamentals for Multi-Band Design Essentials Training by Tonex
From HF through millimeter-wave, multi-band systems demand design choices that balance physics, regulations, and mission realities. This course grounds participants in the fundamentals of spectrum-spanning RF design so they can make confident, quantitative tradeoffs. You’ll connect wavelength to size, performance, and integration, then map propagation differences to antenna strategy, front-end architecture, and link budgets across terrestrial and space environments. The curriculum also highlights contested-spectrum realities—jamming, interference, and spectrum sharing—and how they shape resilient designs. Security matters too: RF pathways are attack surfaces, and poorly protected links can leak intelligence, enable spoofing, or disrupt operations. We address cybersecurity-aware RF engineering, secure waveforms, and hardening tactics.
Learning Objectives
