What is the job description of an rf engineer?

RF Technician Job Description

There are more or less two types of RF engineers, and I have worked as both. The first is an RF engineer working for a cellular operator. They use computer software to model and predict the RF performance of cellular systems, optimize the performance on newly built systems, and/or evaluate and adjust the RF performance of an existing system.

The second type of RF engineer works in R&D as either a board level design engineer, or similarly as a component engineer on a systems level. He or she may also, or instead, work in software developing code to model an RF system, or to actually do the digital signal processing within say a base station, wireless chipset, or other wireless device. Or this type of engineer may work more specifically on a systems level by specifying the design/performance parameters of specific RF components that are sent to other vendors for production.

Regardless of which type one is, expertise in some or most areas of mathematics, electrical engineering, computers, wireless protocols, wireless physical layer protocols, RF transmission lines, antennas, RF propagation, RF test/lab equipment, digital signal processing, wireless technologies and protocols, and simulation SW, to name a few, may be required and used in day to day activities.
