Phase Noise and Jitter - Web Classroom (220)

Timing-related problems associated with signal sources are one of the major bottlenecks in designing today’s highly complex systems. Over many decades, jitter has been extensively studied and utilized to characterize timing inaccuracies in both digital and analog systems. Conversely, phase noise has been exclusively used in RF systems to represent frequency or phase inaccuracy. For both timing and frequency sensitive systems, phase noise measurement is emerging to be the most accurate method of characterizing all types of signal sources (RF, analog or digital). This short course covers the fundamentals of phase noise and jitter, which ultimately set the limit to PLL performance in applications such as frequency synthesis, serial data communication and clock/data recovery. Simple techniques to model phase noise at the circuit component-level and relate it to the overall phase noise and jitter performance of PLLs are presented. The course will also provide a detailed analysis of the different phase noise measurement techniques along with in-depth noise floor analysis. The focus throughout this course will be on providing practical measures utilizing numerous real life examples.

RF Technology Certification - Online (009)

This online program has been designed for applications, production, manufacturing engineers and technicians as well as other professionals who need to have a solid background in the fundamentals of working with RF and wireless products. This four part program provides a thorough understanding of RF analytical tools, communications signals, RF devices and test instruments. Starting with basic analytical tools such as the decibel scale, S-parameters and the Smith Chart, this program covers test instrumentation, RF components, and modulation. A basic block diagram of a transmitter/receiver chain forms the backbone of the course outline. Each component is described, and the relative performance parameters defined. Key impairments are introduced as they become relevant to the operation of the system. Basic system calculations are covered, as well as modulation formats and multiple access techniques.

The program consists of four online sessions spread out over a six month period. Each five to six week session consists of pre-recorded self-paced lectures combined with a live/recorded one to two hour Q&A/tutorial webcast with the instructor as well as forums. Each session has a brief test as well. The program is equivalent to approximately 40 hours of training. After finishing the program students will receive a signed certificate of completion.

Applied RF Engineering I - Circuits and Transmission Lines Online (270)

Based on Les Besser's famous RF course material, this program has been reworked and updated to meet the needs of today's engineers looking for online self-paced study. Video lectures are followed by our exclusive online workbooks featuring interactive problem sets and quizzes along with optional supplemental reading for those who wish to explore topics in more depth. A bonus guest tutorial from a Besser Associates instructor offers a different perspective on one of the topics covered in the course (guest tutorials vary by course offering). This course is the first part of an RF Engineering Certificate program currently under development by Besser Associates.

Even when working with "off the shelf" integrated radio products, engineers still need a basic understanding of circuit operation and design considerations to assure a successful product implementation and avoid unexpected pitfalls. Switching from traditional circuit definitions based on voltages and currents, to power-flow concepts and scattering parameters, this course offers engineers a smooth transition into understanding circuit operation in the RF and wireless domain. We review S-parameter measurements and applications for both single-ended (unbalanced) and balanced circuits. Impedance matching is vitally important in RF systems and we use both graphical (Smith Chart ) and analytical techniques throughout the course. We also examine discrete and monolithic component models in their physical forms, discussing parasitic effects and losses, revealing reasons why circuit elements behave in surprising manners at RF. 

Since wires and printed circuit conductors may behave as transmission line elements, we also cover microstrip and stripline realizations. Another important consideration is circuit layout, therefore we look at problems caused by coupling, grounding and parasitic resistance.
