What is a Radio Frequency Engineer?

A Radio Frequency Engineer, also known as an RF Engineer, is an electrical engineer who specializes in devices that receive or transmit radio waves. All of our wireless and mobile devices operate on radio waves, so our tech-centered society would not be possible without the work of RF Engineers. These Engineers often work in a collaborative environment both with other RF Engineers and stakeholders in other disciplines.

A RF Engineer is a skilled position that requires both a Bachelor’s degree and completion of a state licensure exam. State Licensure is required for an aspiring RF Engineer because so many positions are with public telecommunications companies. Other possible employers include the military or a radio broadcast stations. There also are a limited number of research positions available in academia.

 

RF Engineer Duties and Responsibilities

RF Engineers specialize in designing, implementing and maintaining wireless communication systems. The following duties and responsibilities illustrate what that looks like broken down into tangible tasks

Optimize the Performance of Existing Wireless Networks

Think of how the wireless Internet on our smartphones has gone from 1G to 4G LTE. That progress is the result of RF Engineers running constant evaluations on network KPIs, as well as performing regular maintenance on existing equipment.

Design RF Schematics for New Wireless Networks

Another core duty of the RF Engineer is to design RF schematics for constructing new wireless networks. For those who work in the telecommunications industry, this can involve surveying acquired land for optimal positioning of communication towers. This data is then analyzed and used to create a custom plan for bringing the team’s vision to reality.

Ensure Regulatory Standards are Met

Anyone who works in a regulated industry, such as telecommunications, is required by the FCC to pass a series of State Licensure Exams. RF Engineers use the information learned during this licensure process to ensure complete compliance with FCC regulations.

Analyze Equipment and Identify Areas for Improvement

A fair portion of an RF Engineer’s time is spent out in the field either installing new broadcasting equipment or maintaining current equipment. This includes analyzing equipment functionality and recommending upgrades to decision-makers as necessary.

Communicate Data Using Digital Software

Making sense of wireless network KPIs in a way that decision-makers will understand is an important part of an RF Engineer’s job. According to our research of RF Engineer job descriptions, this is typically done using Excel spreadsheets.

 

RF Engineer Skills

While the role of RF Engineer is highly technical, soft skills like active listening and oral comprehension are integral to success in the field. RF Engineers also have to have the perfect blend of being able to work independently and collaborate with others. Based on our analysis of RF Engineer job postings, here are some common and advanced skills employers desire from RF Engineer candidates.
