Homework : Homework assignments will be given approximately weekly and will be posted on the class webpage. Homework will be by 5:00 p.m. on the specified date on the 3rd floor lockers of MEB near the ECE office (MEB 3280). Homework assignments turned in up to 24 hours late will be penalized 10%. Assignments turned in more than 24 hours late will not be accepted. Home work solutions will be posted after the problems are due.
Homework problems will be graded on a
ten-point scale, with credit being assigned as follows:

Picking up Homework: Your homework, exams and labs will be returned in your student mailbox across the hall from the ECE office. Please sign a sheet allowing us to place your materials there. If you prefer NOT to have your materials left in your mailbox, Sai will hand it over in class. All homework, exams, labs should be returned within 1 week of when they were turned in (not counting holidays/breaks). If they are not, please complain to Sai.
Random Student ID #: You will be assigned a random number, which will be prominently written in RED on the first homework you turn in. Please write this number on everything you turn in. Your grades will be posted on the website according to this number. (We think of you as much more than a number, but probably you’d rather have a secret number when it comes to grades.)
Exams: Exams are closed book. Calculators, laptop computers, tables of integrals, etc. are not permitted. You are allowed one sheet of notes (both sides) for each midterm exam. The notes must be hand-written on standard size (8.5"x11") paper, reduced size photocopying is not permitted. Tentative dates for the midterms:
Midterm I --- Basics, single stage amplifier
Midterm II --- Multistage amplifier, Oscillators
Midterm III --- Oscillators, Mixers
No make up exam will be given (unless permission is granted in advance by the instructor).

(To do well in this class: Keep up in class, study hard, do well on your midterms, and you do not have to take the final exam. But, if you bomb a midterm, or all of them for that matter, all is not lost. You can completely erase mistakes made during the semester and make up your grade on the final.)
ECE 6323 students will have to review an IEEE article and write a one page summary. The articles will be posted in March and the review will be due by the first week of April.
PLEASE plan your schedule so that you have time to learn the material. I am delighted to have the opportunity to teach you about Microwave Circuits, a subject that is truly exciting and magical. I am very confident that you will find many times in your career when you will be able to apply this material, and I hope that you will not only learn from the class but enjoy it as well. J
Disability Accommodations: The University of Utah seeks to provide equal access to its programs, services and activities for people with disabilities. If you will need accommodations in the class, reasonable prior notice needs to be given to the Center for Disability Services, 162 Olpin Union Building, 581-5020 (V/TDD). CDS will work with you and the instructor to make arrangements for accommodations. All written information in this course can be made available in alternative format with prior notification to the Center for Disability Services.
Cheating Policy: Just don't
Here are some things that constitute cheating in this class:
1) Copying someone else's work on an exam. If you accidentally see another student's work on an exam, WRITE a NOTE in your exam and tell me during the exam. Honesty is of great value. You will not be penalized for this. Do not pass any papers to anyone for any reason during the exam. Do not sit near your study partners during the exam. If you use any scratch paper for doing exam problems, please just staple it at the back of your exam. Loose scratch paper could look like notes passed between students.
2) Copying someone else's work on portfolio homework. I hope you WILL work in groups on your homework, labs, software assignments, etc. And I hope that every team member will contribute to this work. If you do not contribute (had to work late and couldn't make the group meeting), then don't copy their work.
3) Copying things (ANYthing) from a book, web, magazine, etc. Give a complete reference and clearly "quote" anything that you want to reference that someone else has done. Even if you don't use their words, but you mention or discuss their ideas, give them a reference. If you are asked to write a report or essay, it must all be in your own work. Just rearranging the words is called paraphrasing. (Paraphrasing is just rearranging the words.) Paraphrasing is also NOT your work.
What happens if you cheat?
Under UofU policy, you could receive an F in the class, be suspended from school, be fined, or be expelled from the university. So just don't cheat.
What happens if someone else cheats?
Statistically, this could lower YOUR grade. Please tell me or the TA or any other professor or TA (anonymously is fine) if you see instances of cheating in this or any other class. The ECE Department is committed to reducing instances of cheating in our labs and classes in order to provide the best possible education for all students.
Errata:
If you find a mistake in the online lecture notes, textbook, solution manual,etc., turn in a copy of the mistake plus your corrections. Clearly label where the mistake occurs, so I can fix it.
