Microwave and RF Design, Volume 3: Networks Third Edition

I really like this book and I ended up ordering the rest of the volumes. The examples and explanations are concise and practical. I use it at my work as an RF design engineer, and it's also great for interviews or hobbies.

dr steer is awesome, def check out these books if you want an actually good intro to RF design, you can even get the pdfs for free if you want

Get all three books if you’re studying engineering
