Hello! This is my first post, personally my experience with TI microcontrollers/dsp is limited to a audio project using a TI DSP that I did few years ago, so, I'm no familiar with TI tools anymore, usually I use other brand's solutions. But now I'm in a project that needs some BT communication and in my reseach about solutions this CC2640 really impressed myself.
I have some experience on designing circuits but usually for bluetooth applications I use modules to have a faster development time. Well, at this time I'm handling a very small application and the CC2640 is perfect to it. As it's small, I needed to make the antenna in the board and I choosed a chip 2.4GHz antenna. This first prototype I'll keep the recomended differential operation, a FR4 double faced board and a the same output impedance circuit as the CC2650EM-4XS application board. As it's my first design on such application I'm trying to reduce the possibilities of some mistake. My question is on PCB design, I needed to bend the trace from the IC to the antenna, is that OK? I avoided right angle corners, but I'm still not so confident if It's fine.
To a next step I'll need to make all this in a flexible board, so probably I'll need to recalculate all inductors and capacitors to this output circuit right? Can you reccomend some study material for me? Usually I try to avoid radio circuits on my boards but recently many projects came to me with this kind of needs and I want to update myself with some signal integrity knoledge on this RF field, more specifically to devices like CC26XX.
