I'm trying to develop a cell phone repeater that can be used at home. I've had some other ideas, and I will probably start with just using two antennas, one for outside my home, and another for inside, and then see if that works. However, I am really interested in making it an active device...
Here's my idea: An antenna on the roof specialized for the frequency of my carrier (850 Mhz). This runs through coax cable to my repeater part, which I believe will consist of a couple gain stages and several filters. Then I have another antenna inside the house.
The only problem is the frequency this is running at. Does anybody know of a good op-amp that has high gain at around 1 Ghz? Or do you think I need to make the gain stages using just transistors and using passive filters. Please let me know what you think!
