 Instructional Material. The lecture slides are detailed and will be the primary
material. The following two textbooks will also be used.

RF Circuit Design: Theory & Applications, 2/E Reinhold Ludwig and
Gene Bogdanov, 2009.

RF Circuit Design / Edition 2 by Christopher Bowick, Cheryl Ajluni,
John Blyler
 Calculators. Many RF problems involve complex number calculations, and
matrix algebra is also used. Students are advised to become familiar
with their calculators' capabilities with respect to this.
 Smith chart,
compass, etc. The Smith chart is used extensively in RF engineering.
Students need to have a
drawing
compass, soft pencil, eraser, and ruler for this. With respect to
a compass, it is probably better to stay away from very inexpensive ones.

 Notes on RF construction techniques
 Preliminaries I (review of
units, complex numbers, dB, wire)
 Preliminaries II (skin and
proximity effects, inductors, inductance formulas)
 Preliminaries III (Litz wire,
inductors and capacitors at high frequencies, Q factors, parallelseries
conversions)
 Preliminaries IV (resistors,
thermal noise, transmission lines as capacitors and inductors)
 Transformers
 Impedance Matching I
(capacitive transformer, resonant capacitive transformer, L match networks)
 Impedance Matching II (T
and PI match networks)
 Active Components I
(diodes, Schottky diodes, reverserecovery, PIN diodes)
 Active Components II
(steprecovery diodes, JFETs)
 Active Components III (BJT
parasitics, junctionand diffusion capacitances, basespreading resistance,
highfrequency models, transition frequency, Miller effect, FETs at high
frequencies)
 Active Components IV (CE,
CC and CB amplifiers, cascode configuration, dualgate FETs, singletuned
amplifiers)
 Two Port Networks I (3/2) (review
of z, h, and y parameters, introduction of ABCD parameters)
 Two Port Networks II (Finished
3/25)
 Superhet and Mixers (Finished 4/21)
 Tuned Amplifiers and Multipliers
Homework is due 7 days after being assigned. Sometimes the schedule is
adjusted slightly to account for exams, holidays, etc. Students get one homework
"free". This means that I drop the worst homework score when I compute the
final grade. Thus, if you miss an assignment for any reason (sick, car
broke down, etc.) , simply cash in the free assignment.
 There will be periodic tests
after we finish a module, on average every two weeks. These tests account for a significant
portion of the grade (see below).
 There will be impromptu quizzes. As with the homework,
students will get one quiz "free", see above.
 The midterm is scheduled for Friday, March 13.
 The
Registrar has not set the date for the final exam.

Students interested in a "nohomework option" should
let the instructor know. With this option, the midterm will account for 25%.
We will design and build a AM radio and a RF power amplifier in this course.
I will post details later.

equations and formulas relevant to the course
 Chemandy Electronics has a collection on Javascript
calculators.

Formulas and Javascript calculators for common inductances and
capacitances.

website of the authors of the main text (RF Circuit Design: Theory & Applications)
used in this course. There are links to the figures in the text as
well as links to the Matlab Mfiles.

 Utilities for designing L,
T, and PI matching networks, also accomodates complex terminations.
