All there is to it really is two SMA connectors, the chip itself and a 2.5V linear voltage regulator.
Lacking proper RF test gear, the only way for me to see if it works is if I can receive something using a cheap rtl-sdr and a ceramic patch antenna.
I want to try to build some simple GPS decoder in gnuradio, maybe I'm biting off more than I can chew here.
I don't have a lot of knowledge about doing PCB layout at these frequencies (controlled impedance/transmission line) so I simply went with the KiCAD transmission line calculator and adhered to the measurements it had calculated for me. The rest is essentially the same as on the Avago application board. I wasn't sure about the via stitching so I simply did it like I had seen it on other LNA boards. Maybe I could've even added more vias. We'll see how it performs.
