New RF Design Course

Besser Associates is pleased to announce two newly redesigned courses providing comprehensive coverage of RF circuit design skills. We have taken material from two five-day courses (our popularĀ Applied RF Techniques 1 and 2 programs) and condensed it down into a live online series (five 90-minute sessions) followed by a separate five day classroom course.

The first course, RF Design: Core Concepts will be presented as five 90-minute session via WebEx March 17-21. It presents core concepts essential in understanding RF technology and presents circuit-level designers with the foundation needed to work effectively with high frequency electronics. Participants gain analytical, graphical (Smith Chart), and computer-aided techniques to analyze and optimize RF circuits in practical situations. This course reviews traditional circuit definitions based on voltages and current and transitions to power-flow concepts and scattering parameters (S-parameters) used in the wireless domain.

This second course, RF Design: Applied Techniques, covers the most popular subjects from the Applied RF Techniques I & II courses in a single five-day live course. This program was developed by request for our on-site corporate customers and is now being offered as a public course.

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. Filters, resonant circuits and their applications are reviewed through filter tables and modern synthesis techniques, leading into matching networks and matching filter structures. Since wires and printed circuit conductors may behave as transmission line elements, we also cover microstrip and stripline realizations. 2D and 2.5D electromagnetic field simulators are used in the course to illustrate transmission line behavior and component coupling effects.

In the area of active circuits, we first examine fundamental limitations posed by noise and distortion. The next topic is small-signal linear amplifier design, based on scattering parameter techniques, considering input/output match and gain flatness RF stability is examined both with S-parameters and also with the Nyquist test using nonlinear device models. Since DC biasing affects RF performance, we review active and passive bias circuits and see how they can be combined with impedance matching circuits. Another important consideration is circuit layout, therefore we look at problems caused by coupling, grounding and parasitic resistance. Narrow and broadband designs are compared, using lossless and lossy impedance matching as well as feedback circuits. Low-noise amplifier design is illustrated, discussing trade-offs among gain flatness, noise, RF stability, and impedance match. Harmonic and inter-modulation performance is also examined. Performance trade-offs of balance d amplifiers are viewed. The course concludes by examining large-signal and ultra wideband feedback amplifiers.

Circuit level engineers will master the latest linear and nonlinear design techniques to both analyze and design transceiver circuits. System engineers will examine block level circuit functions; learn the performance limits and how to establish specifications. Test engineers will learn how to test and evaluate circuits. Transceiver circuits to be covered include power amplifiers, oscillators ( PLL, VCO, etc. ) and the critical receiver elements. Receiver architecture and synthesizer design to meet critical requirements will be presented. Techniques to successfully integrate circuit functions at the system level will be discussed.
