I'm considering taking an RF circuit design class that would focus heavily on transmission lines and microwave circuits. It's supposed to be a tough class but I think I would enjoy it because I really like E&M. The problem is that if I take this class I won't be able to take a photonics class due to scheduling conflicts. Ultimately, I plan to go on to graduate school and focus on photonics, it's unlikely that I will be doing any RF or microwave engineering. Anyone have any strong thoughts on which class I should take? The RF class seems like a nice little diversion but I don't know if I'll really be putting myself at a disadvantage. I realize that graduate schools don't necessarily expect incoming students to have taken a bunch of courses already, but it's a very difficult decision because I think I'd enjoy both classes. In terms of employment prospects for undergraduates, I would assume that having microwave engineering knowledge would be much more useful than knowing a lot about semiconductor lasers/optics.
