WiFi RF Amplifier?
« on: December 18, 2023, 10:38:15 pm »
[This]() recent GreatScott video got me thinking about RF amplifiers and using them to convert an indoor 2.4-5ghz wireless access point to an outdoor one with a power of ~5w (which is legal in many countries, IF used outdoors).

However browsing AliExpress, it appears that many RF amplifiers appear to be unable to amplify both 2.4 + 5GHz. I think some access points utilize a single antenna to output both 2.4 + 5GHz? Or is it always separate antenna?

Has anyone attempted this before?

Um, yes for some. Ex, 4W output power.

That 36dBm (4W) level quoted is the EIRP power, which takes into account the gain of the antenna, The actual power of the RF amplifier is only around 600mW (28dBm aggregate).
