This online short course will give you a good grounding in a range of RF (radio frequency) devices including the fundamentals of device physics, RF circuits, system architectures and noise measurement techniques.
You'll learn about impedance matching, stability and noise figure for amplifier circuit design.
This will be consolidated with a full-day computer simulation exercise where you'll perform RF amplifier design tasks using the industry standard software package Agilent ADS.
The course is run by UCL's Department of Electronic and Electrical Engineering.
Who this course is for
The department's short courses/CPD modules are aimed at those working in the telecommunications industry such as researchers, engineers, IT professionals and managers.
They're particularly suited to graduates in electronic and electrical engineering, communications engineering and computer science who want to further their knowledge on a particular topic, or work towards a Master's degree.
You don't need to have any pre-requisite qualifications to take this course.
You'll cover the following during this course:
- Introduction to RF spectrum, applications, devices and fabrication technologies

Teaching, assessment and certificates
All teaching will be online and involve a mixture of pre-recorded lectures and live seminar and tutorial sessions.
The course runs over four days, with 6 to 8 teaching hours per day. This is followed by a tutorial and an optional online exam.
If you complete the course but not the exam, you'll receive a certificate of attendance.
If you take and pass the exam you'll get a certificate stating this, which includes your pass level.
