I like your link spartex..."electronic warfare (EW) technologies", so prescient as Israel will be entering Gaza at any moment now.
What is a Radio Frequency or “RF” Engineer? The short answer is that RF Engineers are research and development (R&D) electrical engineers who specialize in designing, developing, testing, and deploying innovative new wireless networks and radio frequency (RF) payloads, subsystems, wireless networks, and component technologies for use in aircraft systems, spacecraft and satellites, missile systems, maritime crafts, and land-based defense platforms. This often includes the RF and/or microwave systems architecture, components, advanced circuits, and other products, from transmitters, receivers, and antenna arrays to frequency synthesizers, amplifier modules, switch matrices, and more. While traditional RF Engineering typically focuses expressly in the megahertz (Mhz) range, our advanced RF professionals exploit that range and up into optical systems to deliver the most powerful and effective solutions for national security, space exploration, secure communications, global navigation, commercial systems, civil infrastructures, electronic warfare (EW) technologies, and more.
Beyond the scope of the R&D world, there are also RF Engineers whose primary responsibility is planning, setting up, monitoring, and suggesting improvements to wireless networks for cellular providers to assure that customers receive the speed and coverage they were promised. There are many of those RF Engineers working today due to the worldwide popularity of cell phones and smart TVs, but those engineers typically use existing technologies to achieve particular functions and are not involved in the design or development of advanced new RF equipment.
