Often cited as the RF engineering Bible, this book covers core concepts related to microwave engineering. Pretty much every concept I have learned regarding the subject is partly due to this masterwork.
However, it is not without flaws. While I can appreciate the dedication, I am personally not a fan of the derivation heavy sections (which seems to be a common complaint about the book). Also, I am slightly disappointed that each subject couldn't be covered more in depth, but I do realize that if this were the case the book would be around several thousand pages.
The examples and additional problems are a very helpful for putting your knowledge to the test. In general it's an excellent RF reference book to have sitting around in case you need it.
Like most Wiley books I have seen, it is very expensive. However, pdf copies do exist on the clearnet (including archive.org). The solution manual is also very easily found should the need for that ever arise.
Great book in my opinion. Much easier to approach and digest than Pozar. Lee's style of writing is a breath of fresh air compared to other authors. Less bogged down in math and thus more suitable for non-students.
I do like how when discussing RF amplifiers he goes into how to bias them. This is something I see skipped over even in dedicated RF amplifier books. The Appendicies are also very good.
Ah, the book every electrical engineer has read. Personally, I think this is a terrible introductory text to electronics due to the fact that it's just way too technical for an undergraduate to appreciate.
However, once you are experienced with analog electronics this book is invaluable to have as a reference. Parts II, III, and IV are in a league of their own compared to other general electronics books.
The way I approached having to deal with this book in undergrad was using it as a "second opinion" of sorts to compliment other, simplier books.
However the problem sets are where this book really shines and I reckon its worth picking up for that alone.
I am well aware of the absurd amount of editions this book has, my experience was with the 6th.
