LTC5587 RF Power detection circuit

Hello, 

I am currently in school and am looking to do a project which involves measuring signal strength of my own designed antenna. Unfortunately I am new to RF and was wondering if the LTC5587 chip is suited for this task.

The antenna is multiband at 2.4GHz and 5.8GHz. I am having trouble understanding the example circuit in the datasheet. How would i connect my antenna to the chip? Do I need to use an SMA connector from my antenna to the chip? How would that work. 

I am assuming I can use the capacitor values in the datasheet corresponding to the two frequencies. Do I need to change the capacitors if I want to use one frequency over the other?

Any advice would be greatly appreciated.

Thanks,

Jacob Aldred
